Paleoptera

“Old wing” An ancient group of insects within the Class Insecta. Dragonflies and Mayflies are part of this group, they are also missing the ability to fold wings over their abdomen.

Neoptera

“New wing” A more recent group of insects that can fold their wings over their abdomen.

Hamulate Coupling

A toothed structure that connects the forewings and hindwings of insects, allowing them to function as a single aerodynamic surface during flight.

Amplexiform Coupling

A type of wing coupling mechanism in insects where the forewings and hindwings overlap extensively, increasing the wing area and aerodynamic efficiency during flight.

Integument

The outer protective layer of an insect, including the cuticle. It provides physical protection and helps prevent water loss.

Ecdysis

The process of molting the exoskeleton in insects and other arthropods. It allows the insect to grow by shedding its rigid outer layer and forming a new, larger one.

Exuviae

The cast-off skin after molting in insects and other arthropods.

Spiracles

The external openings of the respiratory system in insects. These openings allow air to enter the trachea, facilitating gas exchange.

Trachea

Large Network of tubes that are connected to the spiracles and branch throughout the insect body, delivering oxygen directly to cells and tissues.

Tracheole

Connected to the trachea, these are the fine terminal branches of the respiratory system in insects. They extend to individual cells, facilitating direct oxygen delivery and carbon dioxide removal.

Open Circulatory System

Hemolymph is not confined to vessels but circulates freely

Hemolymph

The insect equivalent of blood, does not transport oxygen, only vitamins and nutrients.

Heart and Dorsal Vessel

The large organ that runs along the dorsal side of the insect. It is a simple tube-like structure with valves that pump hemolymph around the body.

Antennae

Used as primary olfactory receptors (smell) and chemoreception (taste)

Holometabolous

Complete metamorphosis: Egg>Larva> Pupa>Adult

Hemimetabolous

Half metamorphosis: Egg>Nymph>Adult

?

Larva

Pupa

What do insects get out of pollination?

Food in the form of sugars and proteins from nectar

What do plants get out of pollination

Aid in pollen transfer for sexual reproduction

Termites, ants, bees and wasps are all forms of what?

Eusocial insects

Cordyceps fungus
