ENTM010 Part 2

  • Dance language of honeybee – Bees “dance” in circles or figure 8s to show others where food is.

  • Diapause – A pause in development (like insect hibernation) during bad conditions.

  • Disease and body louse – Lice can spread diseases like typhus to humans.

  • Diversity in insects – Insects are the most diverse animal group, with millions of species.

  • Diving beetle feeding habit – These beetles are aquatic predators that eat insects and tadpoles.

  • Dung beetle biology – These beetles roll and bury animal poop, helping fertilize soil.

  • Ecdysone – A hormone that controls molting (shedding old skin) in insects.

  • Ecological advantages of dipteran insects – Flies help by pollinating, breaking down waste, and being food for others.

  • Ephemeroptera – Mayflies; short-lived adults with aquatic larvae.

  • Etymology of Hymenoptera – “Hymen” means membrane, “ptera” means wings (wasps, ants, bees).

  • Etymology of Lepidoptera – “Lepido” = scale, “ptera” = wing (butterflies and moths).

  • Eusociality – Extreme teamwork; some insects (like ants) have queens, workers, and soldiers.

  • Evolution of hexapods – Hexapods (six-legged insects) likely evolved from crustacean-like ancestors.

  • Fire ant adaptation – Fire ants form living rafts in floods and have painful stings.

  • Firefly bioluminescent organ – Fireflies have light-producing organs to attract mates.

  • Fly response to a corpse – Flies are among the first insects to arrive at a dead body.

  • Foraging strategies in Myrmicinae – These ants use trails and teamwork to find and collect food.

  • Forensic entomology – Using insects to study crimes, especially time of death.

  • Formic acid – A chemical ants use for defense or attack.

  • Function of Malpighian tubules – Organs that remove insect waste (like kidneys).

  • Glucosinolates – Chemicals in mustard/cabbage plants that deter herbivores.

  • Gossamer-winged butterfly – A group of small, delicate butterflies like blues and coppers.

  • Gulf fritillary – A bright orange butterfly found in the southern U.S.

  • “Hair-pencils” in butterfly – Scent-releasing structures used by males to attract females.

  • Haltere – A small knob that helps flies balance when flying.

  • Hamulate wing-coupling mechanism – Tiny hooks that connect wings in bees and wasps.

  • Harvester ant – Ants that collect and store seeds for food.

  • Hemolymph functions – Insect “blood” that moves nutrients, hormones, and helps with immune defense.

  • Holometabolous – Insects that go through complete metamorphosis: egg, larva, pupa, adult.

  • Hornet – A large, social wasp known for strong stings.

  • Hornworm – A big caterpillar that eats tomato plants.

  • Horsefly feeding – Female horseflies bite animals to suck blood.

  • Hydroquinone – A chemical in some beetles used for defense sprays.

  • Hymenoptera biology – Insects like bees, ants, and wasps with complex societies and stingers.

  • Hymenoptera sex determination – Males hatch from unfertilized eggs, females from fertilized ones.
