Aquatic insects

Aquatic insects live some portion of their life cycle in the water. They feed in the same ways as other insects. Some diving insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete.

Breathing

One problem that aquatic insects must overcome is how to get oxygen while they are under water. All animals require a source of oxygen to live. Insects draw air into their bodies through spiracles, holes found along the sides of the abdomen. These spiracles are connected to tracheal tubes where oxygen can be absorbed. All aquatic insects have become adapted to their environment with the specialization of these structures.

Aquatic adaptations

1.Simple diffusion over a relatively thin integument.

2.Breathing from a plastron or physical gill.

3.Extraction of oxygen from water using a plastron or physical gill.

4.Storage of oxygen in hemoglobin molecules in hemolymph.

5.Taking oxygen from surface via breathing tubes.
