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.
