This makes it difficult for predators to see them. What do grasshoppers eat? Some grasshoppers eat flowers. The pollen and nectar give them a lot of energy. Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among As hemimetabolous insects, they do not undergo complete metamorphosis; they . body lengths) without using its wings; the acceleration peaks at about 20 g. Energy is put into the store at low power by slow but strong muscle. Grasshoppers can jump far with their two long hind legs. 4.

Grasshopper Springs. Where does the grasshopper keep its catapult? break, but it is very bendy and flexible, and would be no use at all for storing energy. Most grasshoppers are pretty strong fliers, and will make good use of the spring to release its energy and catapulting its body into the air. Aristophanes wrote in amazement about how far fleas could jump [Ref. . Grasshoppers, which have their energy storage devices in their legs, use their ‘ hip’. What do caterpillars like to eat most, and what is their favorite leaf to feed on? There How do grasshoppers use their body parts to survive?.

Archsim Energy Modeling
Archsim Energy Modeling is a plugin that, for the first time, brings fully featured EnergyPlus simulations to Rhino/Grasshopper and thus links the EnergyPlus simulation engine with a powerful parametric design and CAD modeling environment.
Archsim allows you to effortlessly create complex multi-zone energy models, simulate them and visualize results without ever switching between tools. Archsim supports advanced daylighting and shading controls, ventilation modules such as wind and stack natural ventilation, airflow-networks, simple HVAC, photovoltaics and phase changing materials. It is typically used for rapid early design exploration where building shape, window to wall ratios, facade and glazing systems and passive approaches such as shading and natural ventilation potential are tested for their impact on the building environmental performance and comfort.
Simulation inputs such as model geometry, materiality, constructions and zone usage profiles are fully parametric and can be coupled with optimization algorithms within Grasshopper.
Archsim is a young tool under heavy development and new features are added frequently. Archsim exports native IDF files that are fully customizable. Besides EnergyPlus version 8-1-0 support the same workflow can also produce TRNSYS B17 files.
Documentation and example files, community support and most importantly a copy of Archsim are available under www.archsim.com
I’ve been experimenting with ArchSim in conjunction with ladybug. It seems to work great with simple geometries, however I currently have a model that I can’t seem to troubleshoot. It consists of 8 glass “blobs” supporting single canopy. I want each blob to be it’s own thermal zone, with the only enclosure material to be the glass. And then I want to be able to run an e+ simulation based off that criteria. See attached files and images, you may have to relink a different weather file to test. Your help is much appreciated!

I have got a problem when using Archsim,
When I connect model zone, window to the Networker, it comes: You model unit system must be in meters. However, my unit in rhino is in meters. Anyone knows the reason?
Late summer is grasshopper season for me. Even though grasshoppers are around from the first hint of spring to the last days of autumn, it seems like it’s in the hot, dry days of late August and early September that grasshoppers are most notable. Here at our new house, we wander back through fields of long grass when we go for a walk. Each step scatters a half a dozen grasshoppers from before us. They bound away, some just a foot or two, some four or five, and the odd one spreads its wings and flies off much farther.
Many of the non-fliers may still be nymphs, lacking full-grown wings, but all are very proficient jumpers. They owe this to their thick hind legs which contain strong muscles. There are two phases to the grasshopper’s jump: a crouch, and a thrust. As the grasshopper crouches, it contracts its flexor muscle to pull the lower leg tight to the upper leg. In doing so, it also flexes a bit of cartilage that acts like a spring, storing energy. Just before it releases the flexor muscle it contracts the extensor muscle, so that force is already being applied. When it releases the flexor, the “spring” snaps back, the extensor muscle contracts, and the leg kicks out rapidly and with great force. An analogy might be a catapult. As the catapult arm is winched back, it stores up considerable energy. When the winch is released, the catapult arm snaps back. If the body of the catapult was extremely light, and the catapult arm was braced against the ground instead of pointed at the sky, the mechanism would be capable of thrusting the catapult great distance (instead, they put a cup on the end and it thrusts other objects great distances).
If we could jump the same distance relative to our body length that a grasshopper can, we would be able to throw ourselves around 40 meters/yards in one leap from a standstill. At peak acceleration the grasshopper is experiencing about 20 G’s of force – a grasshopper is built to withstand this, but the same force would probably smush a human flat.
I thought I would try to see how many species I could spot amongst our grasses in the meadows. I took photos of everything that seemed to look different, with the intention of identifying them all when I got back inside. It seemed that the vast majority of the individuals I was seeing were of the above species. It was so boldly marked, I didn’t figure I would have any trouble at all identifying it, but I never did find a name. Of the dozen or so photos I cropped and edited, though, I was only able to place labels on four. Four, that’s all!
I pulled out my Kaufman Insects, but for all its fabulousness in other departments, it seems to be lacking in the orthopterans. So I next turned to my Marshall Insects, which helped me to identify (with confirmation provided by BugGuide.net) three of the photos. Then I ran out of print references, and tried browsing BugGuide.net. I was astounded at how many species there were, virtually all of them looking similar to the others. Finally, I searched for a list of Ontario grasshoppers, and found one for the Ojibway Nature Center in Windsor that I was able to identify one more species from. But whew. I hadn’t expected it to require such effort!
I get the impression that identification of grasshoppers from photos can be a tricky thing. For many the field marks are subtle, or you don’t know to look for them when taking the photo (such as with the tree cricket). Of course, as with all insects, there are always some that can only be identified by careful examination of their genitalia or other features requiring a microscope. And then, just to throw an extra wrench in the works, nymphs don’t always have the same pattern as their parents. I had originally thought that the grasshoppers might not be too hard to figure out, but now I’m thinking perhaps they’re a group best left to the experts, like flies or ants.
That said, here’s a couple of the more distinctive species I had. This one was the easiest to ID. It’s a Roesel’s Katydid, also called Shield-backed Grasshopper, Metrioptera roeselii. Its thorax has that yellow-edged flap that seems to fold down over the sides of the body. It’s a recent import from Europe, first found in North America in 1953, in Montreal. It’s now found throughout much of the northeast. Apparently there are both long- and short-winged forms, with the long-winged more common here. This one is a short-winged.
I believe this one is a Red-legged Grasshopper, Melanoplus femurrubrum, although there are a couple of Melanoplus species that share this feature, and I’m not clear on how to differentiate them. Migratory Grasshopper, Melanoplus sanguinipes, would be another possibility, although it seemed like they generally had more pigment in the herringbone pattern of the hind legs. Both Red-legged and Migratory are fairly widespread species, with BugGuide.net having records from coast to coast.
Another Melanoplus species (I think) that I’ve labeled Red-legged but could be something else. This one has more black markings in the wings, and a different pattern to the face. Individual variation? Separate species? I don’t know.
This might be a nymph of yet another Melanoplus species, M. differentialis, Differential Grasshopper. I stumbled across one in the nymphs section of the BugGuide.net Melanoplus page that looked very similar. It stood out from most of the others that I saw in its bright greenish-yellow colour. The majority of the grasshoppers I encountered were primarily brown.
Speaking of nymphs, I came across a couple of these in the grass. They’re the shed exoskeletons of grasshopper nymphs as they molted from one instar to the next. Based on poking around the nymphs page I think that these (as well as the second photo in the post) were late-instar (either fourth or fifth) nymphs of Red-legged Grasshoppers. I gather the black and white arches across the shoulder of the nymph are typical of many Melanoplus species.
Another exoskeleton. Like dragonflies or cicadas, grasshoppers have incomplete metamorphoses, hatching into adults directly out of their last-instar skins, without going through a pupal stage. As nymphs they have wing “buds” but their full-grown wings and full-length antennae don’t appear until the adult stage.
This last one isn’t actually a grasshopper, but another tree cricket, a different species from the one I posted about a few weeks ago. I found this one tucked in the leaves of a milkweed. It seems to be a Black-horned Tree Cricket, Oecanthus nigricornis, identifiable by the dark antennae, dark legs, and markings on the thorax. This species tends not to spend much time in trees, instead preferring raised vegetation in meadow habitat, giving it the alternative common name of Prairie Tree Cricket.
The grasshopper is a medium to large sized insect and the grasshopper is found (close to grass) all over the world. Grasshoppers are best known for their ability to jump incredible heights and distances.,
Most grasshopper individuals grow to about 2 inches long although larger grasshoppers are found on a fairly regular basis that grow to more than 5 inches in length. The grasshopper has wings meaning it can migrate over long distances when the weather gets too cold.
There are 11,000 thousand known species of grasshopper on Earth, that live in grassy areas such as fields and meadows and forest and woodland. Like all insects, all species of grasshopper have a three-part body that is made up of the grasshopper’s head, it’s thorax and the abdomen. Grasshoppers also have six legs, two pairs of wings, and two antennae.
The antennae of the grasshopper are known to be remarkably long and can often be longer than the grasshopper’s body, although the grasshopper’s antennae and the grasshopper’s body are normally about the same size. Grasshoppers use their long antennae in order to make sense of their surroundings.
Grasshoppers have six jointed legs that are incredibly powerful for such a small creature, as grasshoppers are able to jump extraordinary distances. The two back legs of the grasshopper are long and powerful and are just for jumping, where the four front legs of the grasshopper are primarily used to hold onto prey and to help it to walk.
Despite their large size, grasshoppers are herbivores animals and have a diet that consists solely of plant matter. Grasshoppers eat grasses, weeds, leaves, shrubs, bark and numerous other species of plants that surround them.
The grasshopper is also a stable food source for many predators around the world including reptiles, insects, small mammals and birds. It is common for humans to eat grasshoppers in places like Asia and Africa where the bigger species of grasshopper are found, and there is a less readily available alternative protein source.
The female grasshopper lays an egg pod that contains a couple of dozen grasshopper eggs in the late autumn to early winter depending on the area. The female grasshopper inserts her egg pod into the soil so that it is a couple of inches underground. The grasshopper eggs can take up to 9 months to hatch as they wait until the weather has warmed before breaking into the outside world.
When the first baby grasshopper (known as a nymph) hatches out of its egg, it tunnels through the soil and up to the surface, and the remaining grasshopper nymph follow. As they get older, the grasshoppers will increase in size until they are adults. The grasshopper only remains in this stage (young and adult) for a few months before it dies meaning that most grasshopper indiv >

The “moving wall” represents the time period between the last issue available in JSTOR and the most recently published issue of a journal. Moving walls are generally represented in years. In rare instances, a publisher has elected to have a “zero” moving wall, so their current issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year moving wall, articles from the year 2002 are available.

The Grasshopper And The Ant
The fable of the grasshopper and the ant paints the picture that play is bad and work is good, or at least that living for today gets you into trouble, and planning ahead lets you thrive. Depending on the version you encounter, you may hear morals of prepare for lean times or die, plan for the future, help the needy with your resources, or even something like there’s a time for “work” and a time for “play”. You can’t disagree that having fun is much easier and more satisfying in the moment than working all the time.
The people I observe — on the news, in TV shows (a reflection of social norms or trends), on the streets, and in my own life — seem to live a life of ease and comfort more than a life of effort and challenge. Is that a grasshopper and ant comparison — ease and comfort equating to the grasshopper and the effort and challenge equating to the ant? In some ways yes, but there’s more to it than what Aesop’s simple fable depicts, because life is more complicated today than then.
By “ease and comfort” I mean taking the easy path or the path of least resistance regardless of the consequences, and “effort and challenge” means pushing and extending yourself, and taking care of business and being responsible. Comparisons might be living a “BarcaLounger” life vs living a “rock-climbing wall” life, falling off your healthy diet during the holidays vs staying on your healthy diet year ’round, or going along with the gang rather than doing your chores vs seeing the gang later.
The question is, how much intention, responsibility, and self-control do you live with?
My take is, if you don’t push yourself, and tend to live in ease and comfort, you don’t grow or live a free life. What I mean by “you don’t live a free life” is that you are a captive, or maybe even a slave, to your ego, and that you aren’t being responsible and doing all the things you really want to and can do. Chaos reigns, and you are barely getting by. You may have a lovely life filled with ease and comfort, but you aren’t living to your potential, following your dreams, and calling your own shots. Ego is in charge, telling you what to do or not do, and keeping you reined in.
Examples of being controlled by your ego that you might see in your own life:
* Do you brush as the dentist directs? My dad loves to tell me – and no, he’s not a dentist — that you only need to brush the teeth you want to keep.
* Do you continue to eat ice cream even though you’ve been told to avoid dairy, saying to yourself that it tastes so good and you can’t possibly give it up?
* Is your word gold, are you reliable?
* Have you been told to eat more vegetables but don’t because it’s too hard to learn how to prepare them so you enjoy them?
* Are there health habits you feel you want to adopt but can’t quite muster what it takes to start? Or to continue the habits you started?
* What project have you dreamed and talked about and continued to postpone starting, or finishing?
If you identified with any of those questions, you are falling prey to “ease and comfort”. Resistance is rearing its head to stop you, or at least slow you down, from living the life you want. Your ego is using logic on you to keep you on your path of the easy course. Careful, because that’s a downward spiral that can be hard to pull yourself out of.
The ease and comfort approach to life can be the path of sloth and laziness, obesity and illness, as well as boredom and a poor work ethic. Haven’t you noticed that our society is getting fatter and sicker by the day? Or, that more people seem to have an attitude of “the world owes me”? And that they are easily bored, yet watch ancient reruns instead of tackling or finishing the project they’ve been talking about for years? What are you doing instead of the chores stacking up on your to-do list? Resistance — it’s got you. Ease and comfort are your fallback position, without even thinking. Or worse yet, even with careful thinking, thanks to justification.
In contrast, there is the life of effort and challenge. When you are in the habit of pushing yourself, and “always” taking the challenging path, you grow and impact the world. When you grow, you move to a path of an upward spiral that you can ride to great heights of joy and satisfaction, and success. You see it all around you in others. These are people who provide you great customer service; the ones you cheer when you see them launching into space, competing at the Olympics, winning Nobel prizes, developing technology into things, or making discoveries that will benefit others; politicians who reduce the crime in their communities and clean up the ghettos; teachers who inspire their students to excel; and parents who teach their kids responsibility and manners.
You see this in your personal life too. You lose the weight the doctor urged you to so that your joints don’t hurt and your heart doesn’t have to work so hard. The projects you dream up get started and finished. Not only is the work you were hired to do done well, but you also take that extra step to do more. You create and maintain a health regimen to keep you well and growing strong and younger. Your word is gold: you do what you say you will do. This puts you on the effort and challenge path. This is the path of high performance and success, happiness and joy, and the path of energy and engagement. This is an upward spiraling path that you can ride for the rest of your life.
For most people these lifestyles don’t represent all or nothing. We are all works in progress, and we flow in and out of “ease and comfort” and “effort and challenge”, and back again. What’s important is your attitude. Do you want to be free, to be your own person? Then you have no choice but to select “effort and challenge” as your lifestyle. Using productivity tools will help you stick with that decision and progress toward being a more free person who’s highly productive. You maintain a positive outlook on life and your role in it. A bonus with this pattern is the energy and peace of mind that comes from being truly independent.
Think about how these two paths impact your energy levels. The path of ease and comfort is an energy sucker, while the path of effort and challenge is an energy booster. Ultimately, if you want to live an energized life and experience all that it has to offer, you have to walk the path of effort and challenge, and to be autonomous. Any other choice leaves you a slave to others’ whims and needs, and to your ego and your resistance.
Plus, a Bonus
The last important lesson highlighting these two paths is that of the role model. The path you choose to walk is the path of the role model you play. You teach the people in your life, especially your kids, how to live by the way you live. Do you want your kids to have the best in life? Then you need to model the way by doing your best with your life. To be part of the solution, not the problem, take the path of effort and challenge. That approach models for others that a positive outlook promotes progress. When the role you model is that of not helping with the solution so being part of the problem, you successfully model the path of ease and comfort — guiding them into an unhappy, unhealthy, and unsuccessful life.
Yes, the grasshopper has a great time each day fiddling and singing, relaxing in the sun, and generally hanging out with his buddies. But the grasshopper ultimately needs more in and from life to thrive, so ultimately isn’t as happy as he wants to be. The ant, on the other hand, also enjoys his daily life with working to collect and save food for lean times, overcoming obstacles and challenges, and building for the future of his community. The ant creates a perfect life and thrives, and is quite happy.
The grasshopper’s path of ease and comfort looks great for a brief time. The ant’s path of effort and challenge looks great for a long time. Which are you going to choose?
