Insects
Insects play a very large role in the circle of life on earth. They represent a large population of the animal kingdom. Fascinating to some,creepy to others but always present in our daily lives. Questions about any sort of bug go here.

Do stink bugs go away in the winter?
Yes , and the cold weather kills them amazingly fast too! I had a couple very lively stink bugs in my room and it was 25 degrees outside. I threw them out the window and watched them on my deck because the pheromone released when smashed attracts more of them. They fell over onto their backs and died within 30 seconds. I had them coming through my AC throughout the fall and I'm thinking there could be some mama stink bugs in my room hiding waiting till spring to have their 30 Lil baby stinkbugs. I don't want my house infested with these things so I'm thinking I could seal my room off open the windows and let the room temp drop below 35 degrees for a few hrs, and that would kill all of them. That's how I even came across this ? They are horrible here in western Pa. The rapture of the born again in Christ, and the 7 year tribulationdirectly after is near. Its fitting also because these stink bugs destroy all crops causing massive famines. In turn a loaf of bread will cost a days wages as described in Revelation of the Holy Bible. Stink bugs also feast upon dead flesh, so when ppl die of starvation the critters will be here to clean up. The Mark of the beast is also here check the RFID chip or veri chip that will be mandatory within three years for every citizen to be implanted with under their skin on their right hand or in their foreheads. Without the chip you will not be a part of society with No money No paycheck No food No house and so on. If you take it you will be accepted by man and the beast, however your soul will be damned indefinitely! Its in the health care bill aka Obama care! All this is described in Revelation end times prophesy and it is now here in America! All, repent and ask Jesus the Christ into your heartto save your soul before its too late.... Good luck with them Lil buggers too lol. God bless to all who get this!
No, They do not bite. They are harmless to humans and make a great pet. They live in trees and blend well. You can touch them and they feel like a real stick. Very Cool!!
DDT may stay in the system of porpoises longer than with other animals because porpoises lact the necessary enzymes to break down this type of poison. The use of DDT as a pesticide has endangered many animals in the past, and is not longer being used in the United States.
all insects have 6 legs but spiders and other arachnids have 8
How can these bacteria be used to control insects in crops?
Population decline by natural enemies against target species is the use of microbes to battle plant insect pests. Microbes represent pathogens that disable or kill their hosts. Microbes and predators serve as effective biological controls that biodynamic and organic farmers use along with bait and trap plants, carnivorous and repellent plantings, horticultural oils, insecticidal soaps, organic mulches, and row covers.
How does an insect turn into an adult?
Larvae turn into adults through the process of metamorphosis. This process starts after a larva turns into a pupa. It then emerges from the pupal stage in its adult form.
Why might a geneticist use fruit flies to study how genes function?
Fruit flies have a short generation time, produce numerous offspring, and share many genes with humans. This makes them ideal for genetic studies that aim to understand how genes function and interact. Additionally, fruit flies are easy and inexpensive to maintain in a laboratory setting.
What spiders build hard nests that are mud-like - like bees nests?
In most species, female spiders will spin a thick, protective cocoon for their developing eggs and sometimes the spiderlings once they've hatched. Some species will leave the cocoon unattended while the young spiders develop, and others, such as wolf spiders, will carry the cocoons around with them.
The function of the gastric ceca is to?
In mosquitoes, the gastric caeca are responsible for ion and water transport. In the cockroach, the
gastric caeca contain bacteria which aid in digestion. Leeches store concentrated blood in their
gastric caeca. In grasshopper, chemicals are secreted from the gastric caeca in the stomach and
from the salivary glands. So the general role of the gastric caeca is for digestion, but without
knowing the species, your question is a little difficult to answer.
What are some examples of solitary insects?
Some examples of solitary insects include praying mantises, beetles, and certain species of bees such as digger bees and sweat bees. These insects typically live and forage alone rather than in social groups or colonies.
Are earthworms animals or insects?
Earthworms belong are Annelids which belong to the Kingdom Animalia so technically they are animals.
Insects are also animals (Animalia). But no, earthworms are not insects.
Why does grasshopper lay eggs in underground?
A grasshopper most often lays its eggs on the underside of blades of grass and leaves. The eggs are generally laid in clusters.
What does the Bt gene produce and how does it affect insects that eat plants that express the gene?
The Bt gene produces a soil-inhabiting bacteria. This bacteria is known to be made into insecticides and kills insects that eat plants with the Bt genes.
Both, depending on the bug. Some bugs are attracted to heat, like sandflies, and some others are attracted to light, like moths.
There are even more things that bugs are attracted to. Mosquitoes are attracted to carbon dioxide, a gas that you produce by breathing out!
Which insect causes elephantiasis?
Elephantiasis is usually caused by a blockage of the lymphatic system by threadlike filarial worms, Wuchereria bancrofti.
Everybody is familiar with Grandaddy Long-Legs with the long, slender gams and little egg-shaped bodies. These fascinating little characters are related to spiders, but they are not spiders. Here is the good news--THE ARE ABSOLUTELY NOT POISONOUS and are completely harmless to humans, so we can toss that old myth right out the window. They do not have venom glands or fangs, and their grasping claws, typically very tiny, are not strong enough to break human skin. So, no need to worry any more.
The most obvious difference between spiders and Opiliones, also known as Harvestmen, is that spiders have a body divided into two parts, whereas the Opiliones' two parts have fused into one so they do not have the alluring waistline of a spider. Opiliones also have no spinnerets for making silk or webs, so if you see one in a web, it is most likely about to be food. Unlike most spiders that must liquefy their food, Opiliones can eat chunks of food. Spiders have eight eyes while Opiliones have two eyes that perch on a bump atop their head aiming outward. They have a heart that pumps blood (hemolymph) and a brain.
Opiliones and spiders are of the Animal Kingdom and both are Arachnids, but spiders are of the Order Aranaea and Opiliones are an Order all their own called, simply, Opiliones. Neither spiders nor Opiliones are insects. Opiliones are most closely related to mites, ticks, aphids, scorpions, and pseudoscorpions. It is believed that Opiliones are helpful to the environment.
Opiliones are extremely old, coming from a genealogical line going back at least 410 million years to earth's geological Silurian period. Apparently they first lived in the oceans but decided to leave the water around this period. Remarkably, the oldest fossils, which were found in Scotland, have barely discernible differences to modern Opiliones. It is an astounding achievement to have survived so long.
Opiliones have adapted to many micro-climates all over the world but they like damp forested areas the best (such as around a lake.) They are greatly diverse in size, colors and behavior adaptations. Adults usually hide during the day and begin foraging at twilight. They remain hidden throughout winter and are most commonly seen in late summer and fall, which is probably how they got their name. Many species of Opiliones tolerate their own kind and will form aggregations up to 200 or many more. This may be a protection against climate and against predators, with the effect of strength in numbers. It could also enhance their group stink bomb.
Opiliones are omnivorous and will eat plants or prey. They scavenge dead organisms or ambush those that are slower and smaller. They catch prey with their tong-like pincers (in place of fangs) near the mouth, with which they dismember their food. Opiliones eat small insects, snails, caterpillars, veggies, fungi, carrion and dung, plus juices and material from plants and fruits. This varied diet is unusual for arachnids as arachnids are usually pure predators. Opiliones, in turn, are also food for birds, spiders and others.
Unlike spiders, most Opiliones breed directly. In some species the male may guard the female after mating and some may defend territories. The female may lay eggs soon after mating, or it may not be until months later. Some lay eggs on the ground, under stones, or in crevices of wood, and some build nests. In some species only the male takes care of the eggs, cleaning them regularly, and often guarding them against egg-eating females. The eggs hatch any time after 20 days or up to six months after being laid, depending upon temperature and species. Most hatch in the Spring, looking like tiny adults, then there are usually six nymphal stages to maturity and they must moult a hardened outer covering each time (exoskeleton) in order to grow. Most Opiliones live about one year in the Northern U.S. and most die in the winter after eggs are laid.
Some of their enemies are birds, mammals, amphibians, spiders, mites and ants. Defenses depend on the species and include shaking their bodies, feigning death by becoming rigid, or gluing debris onto their bodies. Opiliones are usually agile and fast, but if grabbed by a predator, many can easily release a leg that will keep twitching, most likely to confuse the attacker while the Opilione makes his getaway. Unfortunately, the leg will not grow back. The Opiliones' wickedest and best defense is their odiferous (prosomal) stink glands that are used to deter predators, but only as a last resort as it is a high energy cost. It may also serve as an alarm pheromone for others.
There has been a lack of research on Opiliones and the information is challenging to piece together, but there is much more about them that is not included here. I started this to simply find out if Grandaddy Long-Legs really are poisonous as is popularly believed and quickly found myself up to my nose in a sea of peculiar names that are barely spellable or pronounceable. But, even after the close call with drowning in all the alien minutiae, I began to appreciate these little guys. Still, I prefer that they stay outside of my house; but I will certainly think twice before harming one now.

Does a grasshopper have an amniotic sac?
Grasshoppers do not have an amniotic sac. Animals with amniotic sacs are mammals and birds that have a sac for the fetus to grow and gain nourishment from.
What is the difference between a crustaceans and insects?
Crustaceans are a completely different species of Arthropod, because they have 10 legs, pupils in their eyes, etc. Most types of crustaceans also live in the water, although a few species of insects also live underwater.
How much is a green eyed cicada worth?
It's worth nothing. It may be worth something only if the city you are in offers a prize, but other than that nothing. Zero, nada, nunca, nothing.
Actually they see the world a lot different from the way we see. In terms of evolving, insects are the most advanced in evolution if you think of it. Before dinosaurs evolved into having wings insects mastered the sky, up to now (no matter how advance our technology is) we can't even manufacture or copy the simple web of the spider. indeed in a million ways, insects are always a hundred steps ahead of man. As to your question, different insects see in different ways. a humble house fly sees you in 200+ different angle at the same time. Mosquito can see your body heat even at night. cockroach are blind but their antenna serves as their sense of sight, sense, hearing and smelling all in one. Many other insects are blind but they have their other senses hundreds of times more sensitive than us that they can even predict earthquake faster than our seismograph.
