Classification
Antlions are a family of insects given the zoological classification Myrmeleontidae. The name is rooted in the Greek words myrmex (ant) and leon (lion). The family Myrmeleontidae is part of the order Neuroptera, translated variously as "nerve wings," "net wings," or "sinew wings." All Neuroptera have four wings marked by a netlike pattern of veins. The order Neuroptera, which includes dobsonflies andlacewings, is the most primitive order of insects with complete metamorphosis (Arnett 1985, 249).
Why are they called antlions?
The name "antlion" best describes this insect's predacious larval form—a mottled gray or brown creature with an oversized head, spiny jaws, short legs, and a soft body covered in bristles (see Figure 1).

The larvae of some antlion species hide under bits of debris or wood and attack passing insects.

Antlion adult (Myrmeleon sp.). © 2005 Mark Swanson In sandy regions, some species dig a shallow cone-shaped pit and wait at the bottom for an ant or other insect to slip on the loose sand and fall in, only to be immediately devoured (Arnett 1985, 260). These pit-digging antlions are called "doodlebugs" in the United States because of the designs they make in the sand. As a doodlebug seeks an ideal location to dig its pit, it leaves meandering trails that resemble the random "doodles" of a preoccupied artist (Figure 2). When it finally finds the right place to dig, the doodlebug "draws" a series of concentric spirals, each deeper than the last,

    A pillbug also known as a roly-poly is a small land creature that is often found in many areas around the world. They prefer moist areas often living in soil, under rocks, and dead logs. The pillbug which is an isopod begins its life as a tiny egg and as it grows it sheds its old exoskeleton 4 to 5 times. A pillbug consists of three basic body parts, the head, thorax, and the abdomen. Pillbugs eat decaying plants and animals as well as some living plants. The purpose of this experiment was to learn how to demonstrate the scientific method and to learn if pillbugs are attracted to cornstarch. In this experiment I hypothesize that if a pillbug is exposed to cornstarch and sand then the pillbug will spend more time near the…

    There are about 900,000 known insect species, three times as many as all other animal species together, and thousands of new ones are described each year. They are commonly grouped in 27 to 32 orders, depending upon the classification used. The largest order is that of the beetles (Coleoptera). Next, in order of size, are the moths and butterflies (Lepidoptera); the wasps , ants , and bees (Hymenoptera); and the flies and mosquitoes (Diptera). Other major orders are the true bugs (Hemiptera); the cicadas , aphids , and scale insects (Homoptera); the grasshoppers and crickets (Orthoptera); the cockroaches (Blattodea); and the mantids…

    A two-part study was recently done to show what natural habitat a Pill bug, Armadillidium vulgare, naturally prefers: wet or dry environments along with a light or dark environment. It was hypothesized that a Pill bug would prefer and wet and dark environment based on its natural habitat of soil. For the wet and dry experiment, a coffee filter and soil were placed in each chamber of a double petri dish with one being dampened before being placed in. For the light and dry experiment a light was hung above one chamber of another double-chambered petri dish while the other chamber was covered with aluminum foil, after placing soil in both chambers. An equal number of Pill bugs was placed in each chamber and a study was taken for ten minutes where every thirty seconds the number of Pill bugs in each dish was counted. The results showed that Pill bugs, unlike it’s natural habitats, preferred light and dry environments.…

    Observations: The Velvet Ant is actually a wasp. "Velvet Ant" is the common name for any of a family of wasps whose appearance is similar to that of large furry ants. The wasps live primarily in deserts and hot, semiarid environments. There are thousands of species of Velvet Ants throughout the world, including nearly 500 species in North America alone. All Velvet Ants in North America are parasites. They invade the nest of bees and other wasps, then lay their eggs in the host's cocoon. As adults, the ants feed on green shrubs, cacti, and other available plants.…

    Antz

    • 346 Words
    • 2 Pages

    In the movie Antz, there were a variety of types of governments shown. The main one demonstrated by General Mandible, was fascism or also known as nazism. General Mandible uses his army to make the other ants in the colony behave. There are many different situations shown in this movie to prove that General Mandible uses Fascism or Nazism in this movie. Whereas, on the other hand, Z wants a direct democracy. He wants everyone to say what they have to say and treats everyone evenly. The first reason showing that General Mandible is using a fascism or nazism is that he does not care about every individual ant; he only cares about his colony. He does not care about what any ant has to say and whatever he says, that is what is going to happen. Whereas Z says that everyone should speak out. Also everyone is the same. In the movie, Z says that everyone should think for themselves and that. There are also many other places where General Mandible demonstrates a Nazism or a fascism type of government is that he imprisoned people when they did not so anything wrong. An example of this was when Z ran away and General Mandible imprisoned Weaver. Since Weaver did not do anything wrong, General Mandible should not have been allowed is imprison him. Z on the other hand wants the colony to be run as a democracy. As the colony was making a ladder, Z says that we are a colony, implying that everyone is just as important to one another. Also in the end when everyone gets up safely, he says that we did it, not I did it. There were many other types of governments shown in this movie as well but these two showed the major two in the movie. Even though Z did not use the direct democracy, it is what he wanted to be used and it is what would have been used if Z had been the leader.…

    1. Plot: Garson Poole is the owner of Tri-Plan Electronics. One day, he wakes up in a hospital to find out that he lost his hand during a squib accident. What is worse is that he is told by the doctors that he is a human-appearing organic robot, something called an Electric Ant. Then he learns from a futuristic computer that his subjective reality is being fed from micro-punched reality tape in his chest cavity. He conducts experiments on himself, first by glazing over a couple of holes and then punching new holes to see what effect this has on his reality. The more he starts to know and understand about his reality, he gets even more and more curious about what would happen when he cuts the tape. And when he does, it becomes too late.…

    Termite Lab Report

    • 755 Words
    • 4 Pages

    Termites produce special chemicals within their bodies called pheromones. Because termites are usually found inside dark areas, pheromones help them communicate in these places. Past studies have suggested that ink inside ballpoint pens contains pheromones, causing termites to follow any trail created by the ink. If a pathway is drawn with an ink pen, then a termite will be attracted to the path and trace it due to the pheromones. To test the behavior of termites in relation with the presence of ink, we outlined two shapes with two different writing utensils and timed how long out of a sixty second time period that the termite spent on each path. The results showed that termites spend a substantially longer amount of time following the path of an ink pen than paths made from other writing utensils. The tested termites spent an average amount of 26.9 out of 60 seconds on paths made by the ink pen, but an average of only 2.4 of 60 seconds on a path made by a Sharpie marker. The p-value for the data is 0.00309 for the pen and 0.000214 for the Sharpie marker. The results suggest that termites are attracted to the pheromones contained in ink. This contributes to understanding how termites communicate and travel in areas without light.…
