Ecdysis – correct term for molting/shedding of exoskeleton

Elytra

Entomology

The study of insects

LarvaFeeding 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 advancedAll the most successful orders have complete metamorphosis

Incomplete – young resemble adult

NymphImmature 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 antenna1 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.

TympanumThe “ear” of the insect.
