Lab- Aquatic Entomology questions with verified
answers
Adaptations to aquatic life Ans✓✓✓ -Some breathe straight from the
surface
-Some are small enough to breathe via diffusion of gasses
-A bubble can be carried around with the insect and replenished at the
surface
-Plastrons: bubbles insects carry with them to breathe from
-Larvae of some orders (like Odonata) have gills
-Damselflies = external
-Dragonflies = internal
Feeding Adaptations Ans✓✓✓ -Mouthparts may be modified to filter
food from the water column
-They may also be modified to hunt and grab prey
-Insects may also feed on plant matter by scraping algae off of rocks, or
by feeding on aquatic plants directly
-Can be voracious predators
-Water bug uses raptorial fore legs to hunt, and uses a posterior
"snorkel" to breathe
Movement Ans✓✓✓ -Swimming insects often have modified legs
termed "natatorial"
, -Some insects like water striders have modified tarsal hairs, which allow
them to walk on the surface of the water
Quiz- Aquatic Hemipterans and Coleopterans use their specially
modified legs for swimming. These types of legs are called _____ legs.
