Welcome to “Bug” Week Test scores, not terrible Snack Bar reminder Bug Day is Friday! Use the laptops to get vocabulary and chart done Lab (sketches) and Video coming up
Insect Collection - Tuesday 1. Grasshopper, cricket, roach, mantis 2. true bug 3. cicadas or leaf or plant hopper 4. beetle 5. fly 6. ant, bee or wasp 7. butterfly or moth 8. dragonfly, lacewing, termite, flea, silverfish 9. spider 10. isopod, or centipede or millipede
Chitin – Material that makes up the exoskeleton. Ecdysis – correct term for molting/shedding of exoskeleton
Elytra front wings of beetles modified into wing cover.
Entomology The study of insects
Haltere – modified 2 nd pr of wings in flies.
Larva Feeding stage in complete metamorphosis.
Instar Each of the stages between molts.
Malpighian tubules The excretory structures (“kidneys”) of the insect.
Metamorphosis “Change in form” during growth. Complete – separate stages (larva, pupa) More advanced All the most successful orders have complete metamorphosis Incomplete – young resemble adult
Nymph Immature stage. Resembles the adult to some extent. A stage in incomplete metamorphosis.
Ovipositor Egg laying structure (female only) Becomes sting in bees and wasps
Pheromones Chemical messages, like hormones but released into the environment. Lock and key with receptors on the male antenna 1 mile range!
Pupa Transformation stage where the larva changes to an adult. Special terms like cocoon or chrysalis
Spiracles Openings to the breathing tubes (tracheae) which support respiration in insects.
Tympanum The “ear” of the insect.
General Insect Characteristics 3 body parts, head, thorax, abdomen 6 legs, usually 2 pr. Wings - all from thorax Exoskeleton of chitin Breathe by spiracles/tracheae Wide variety of mouthparts Complete or incomplete metamorphosis Estimates as high as 30 million species
Beetles - Coleoptera Wings - 1st pr. modified into elytra Allow beetles to go places other insects can’t Mouthparts - chewing Metamorphosis - complete - larva often called a grub Other - largest order Weevils, scarabs, mealworms, etc.
Beetles - Coleoptera
Butterflies - Lepidoptera Wings - Scale covered Mouthparts - Siphoning Metamorphosis – Complete, larva called caterpillar Butterflies – wings upright, antenna w/ nobs, narrow body, day active. Moths – wings fold, feathery antenna, wide body, night active. Other – a “skipper” has characteristics of both
Butterflies - Lepidoptera
Ants & Bees - Hymenoptera Wings - 2 pr. Linked, membrane winged Mouthparts - Chewing Metamorphosis - Complete Other - Social, solitary or parasites, 3rd largest Narrow constriction between thorax and abdomen Ovipositor modified into sting
Ants & Bees - Hymenoptera
Flies - Diptera Wings - only 1 pr. 2nd pr - halteres, for balance Mouthparts - lapping or biting Metamorphosis - complete, larva are maggots or wigglers (mosquitos) Other - disease carriers; 4th largest Gnats, midges, punkies
Flies - Diptera
Dragonflies - Odonata Wings - 2 pair Mouthparts - chewing Metamorphosis - Incomplete, aquatic nymphs, rectal gills, jet propulsion Other – predators, even as nymphs Damselflies can fold wings against body, narrow abdomen Legs form a basket underneath Fossil dragonflies wingspan, 2 ½ feet.
Termites - Isoptera Wings - 2 pr. Straight if present Mouthparts - chewing Metamorphosis - Incomplete Other - All social, flagellates are symbiotic Castes include soldiers; 5,000,000 in a colony; huge part of tropical ecosystems; queen might live 50 years
Termites - Isoptera
True Bugs - Hemiptera Wings - half-winged, front leathery, back membranous Mouthparts - Piercing/sucking - beak Metamorphosis - Incomplete Other - plant parasites, predators
True Bugs - Hemiptera
Cicadas - Homoptera Wings - 2 pr, straight if present Mouthparts - Piercing/sucking (plants) Metamorphosis - Incomplete Other – leaf and plant hoppers, 17 year cicada
Cicadas - Homoptera
Fleas - Siphonoptera Wings - n/a Mouthparts - Biting Metamorphosis - Complete Other - all parasites, flattened to move between hairs/feathers Sense heat and jump to host.
Fleas - Siphonoptera
Hissing roaches – sketch plus 3 good facts Mosquito – sketch 3 stages. Mealworm beetle – sketch 3 stages Flea – sketch plus 3 facts butterfly scale – sketch honeybee – notes, (include castes, honey, etc) cricket – sketch plus 3 facts zoobooks – 10 facts you would share Insect Study Lab
