    • What is an Insect?
    • What is an Insect?Insects have an amazing number of differences to their size,shape, and behavior, but they all have 4 characteristics incommon:They have three body parts -a head, thorax, abdomen, and theymust have six jointed legs and two antennae to sense the worldaround them from inside their exoskeleton (outside skeleton).Insects typically pass through four distinct life stages: egg, larvaor nymph, pupa, and adult. Eggs are laid singly or in masses, inor on plant tissue or another insect.There are two general types of insect metamorphosis: simplemetamorphosis and complete metamorphosis.In a complete metamorphosis the wings develop internally duringthe larval stages. The larval stages look quite different from theadult. Between the last larval stage and the adult stage there isa pupal stage which usually is inactive.In simple metamorphosis the wings develop externally during thelarval stages. The larval stages, which are called nymphs, look verysimilar to the adult insect. There is no pupal stage.
    • Insect Myths
    • Insect Myths Insects do not have a history of being loved or well understood:Nineteen centuries ago, when Pliny theElder was writing his natural history inRome, men believed that insects werecreatures without blood, that butterflyeggs were drops of solidified dew, thatechoes killed honey bees, and that goldwas mined in the mountains north ofIndia by a giant ant "the color of acat and as large as an Egyptian wolf."
    • Insect Myths: BEES!•In Wales a bee buzzing around a sleeping child means the child will have ahappy life and a virgin can always walk safely through a swarm of bees.•The Romans believed a swarm of bees was bad luck and that they weredivine creatures which originated directly from the gods.•According to legend the first beekeeper was Bacchus (god of wine), whodomesticated them during his travels in Frakia.•In ancient times it was believed that bees were attracted to the sounds ofclanging metal and thus bees were associated with the love of music.•The Hindu gods Vishnu, Krishna and Indra were referred to as "nectarborn ones" (Madhava) and were often represented as bees perched on alotus flower.•The Egyptian sun god Re was believed to have created bees and humansfrom his tears. Burying the nobility in honey was a common practice in Eygptas a form of embalming the dead. The Eygptians also placed bees and honeyin tombs as offerings to spirits of the dead.
    • Insect Myths: Mantis Mistakes•Female praying mantises have been observed eatingthe heads, and sometimes the rest of their matesduring copulation, but whether the behavior isnecessary or natural remains a matter of debate.•Some researchers suggest that it happens becausestressed-out and underfed females really just needa full belly and some rest after a good bang-session.•Sexual cannibalism seems to happen most often inan artificial or lab environment supporting theabove statement.•A male praying mantid can keep going even if heis beheaded, leading some to believe that withouthis brain getting in the way, a male mantis hasimproved performance and stamina. Others think itmakes him ejaculate faster.

    • Insect Super Powers
    • • Insect Super Powers the heaviest insect in the world is the Goliath beetle from Africa? A big male can weigh up to 100 grams.•A cockroach can live up to nine days without its head.•A flea can jump 130 times its own height.•Some mosquitoes can beat their wings 600 times a second. A midge flyholds the record, with a wing beat of 1046 times a second.•The fastest known insect is a dragon fly that has been clocked at 58kilometres an hour.•There are more than 300,000 species of beetles, making them the largestorder of insects in the world.•Praying mantids are among the few insects which can rotate their headsso they can literally look over their shoulders, making them extremelyeffective predators.•Living scorpions reflect ultraviolet light and can glow with an eeriegreenish color when exposed to UV light, no matter what color theyappear under normal lighting conditions.•The house centipede has the same poison fangs that normal centipedes do,but they can move towards you at great speed thanks to its long spindlylegs. They have a top speed of 40 cm per second.•Incidentally, 40 cm is the exact distance between the house centipedeand your face.

    • Insect Oddities
    • The Beautiful:The Madagascan sunset moth or simply sunset moth, Chrysiridiarhipheus, is a day-flying moth of the Uraniidae family. It is verycolorful, though the iridescent parts of the wings do not havepigment; rather the colors originate from optical interference.In Malagasy, lolo is polysemous for "butterfly" or "moth" and "soul",there is little doubt that this is because a chrysalis resembles acovered corpse and that the butterfly or moth emerges from it—likethe soul from body of the dead. The Malagasy people believe thesoul of the dead or of ancestors appears in the form of aLepidopteran, and thus to attack it is to attack the ancestors.
    • The Beautiful: The Orchid mantis (Hymenopus coronatus) is a variety of flower mantis usually found in Malaysia and Indonesia. They hide in the flowers they resemble, waiting for other delicious insects to alight.
    • The Sneaky: loves ants. It loves them so The antlion much that it digs a slippery, conical deathpit house of fun, just for them. Sweet! Ants that stray into it slip downwards; if they manage to get a foothold, the antlion flicks sand at them so they lose their grip because it’s excited. Fun! When they reach the bottom, the antlion bites hugs them with its massive jaws and injects them with paralysing venom love. Awww! The trapjaw ant: its jaws can open at 180 degrees, and snap shut at between 78 and 140 miles per hour. That’s the world’s fastest bite.
    • The Horrible:The twisted-wing parasite (Strepsiptera) is an order of insects who display agruesome lifestyle. The larval stage parasite will climb a flower and wait foran insect pollinator (bee or wasp) to come along. They climb aboard the bee,burrow into its body, and change into a second-stage larva. They feed off theblood and organs of the host. An adult male parasite will emerge from thehost and search for a mate -a process that takes such little time that henever develops a mouth. The adult female remains in the host’s body for therest of her life, never growing legs or wings. She mates by pushing only herreproductive organs outside of the bee’s body! Her offspring will emerge andlook for new hosts.The gruesome behavior or the male African bat bug (Afrocimex constrictus) isdirected at other bat bugs. Instead of copulating via the female’s sex organs,he will stab her abdomen to release sperm directly into her bloodstream. Sothe females have evolved paragenitals, a “spongy reservoir of immune cells” asa defense against these tactics. But since male bat bugs are not particularwhen it comes to mating, some male bat bugs have also developed paragenitalsto defend themselves against sexual attack!Seed Beetles have rough sex, too, but in the conventional manner. What isvery unconventional is the male seed beetle’s penis (shown in above picture).He can do some damage with that thing. So female seed beetles havedeveloped thicker, more padded reproductive canals over time as self-defenseagainst their paramour.

    • What can insects do for you?
    • EntomophagyThere are, however, some winged creatures thatwalk on all fours that you may eat: those that havejointed legs for hopping on the ground. Of theseyou may eat any kind of locust, katydid, cricket orgrasshopper. –Leviticus 11:21 and 22 Common Edible Insects:Agave Worm, Carpenter, Leaf Cutter and HoneyPot Ants, Bamboo Worm, Bees, Centipedes, Cicadas, Cockroaches, Crickets, Dragonflies, Dung Beetles, Fly Pupae,Grasshoppers, Stink Bugs, June Bugs, Locusts, Lice, Mealworms, Pill Bugs, Rhino Beetles & Grubs, Silk Worms,Scorpions, Tarantulas, Termits, Wasps, Water Bugs, Witchety Grubs, Zaza- Mushi (fly larvae)
    • Insect Dinner Menu from 1855In 1885, Vincent M. Holt published a pamphlet entitled“Why Not Eat Insects” to help persuade his fellowVictorians to give entomophagy a try:In entering upon this work I am fully consciousof the difficulty of battling against a long-existing and deep-rooted public prejudice. I onlyask of my readers a fair hearing, an impartialconsideration of my arguments, and anunbiassed judgment. If these be granted, I feelsure that many will be persuaded to makepractical proof of the expediency of usinginsects as food… My insects are all vegetablefeeders, clean, palatable, wholesome, anddecidedly more particular in their feeding thanourselves.
