What are the uses of the anatomical feature? Flashcards
What is the use of the furcula?
The furcula in springtails (Collembola) is a special forked part that helps them jump. It allows them to leap much farther than you’d expect for their size. This ability helps them avoid predators and move in their surroundings.
What is the use of the cerci?
In insects, cerci are paired sensory organs located at the rear of the abdomen. They primarily serve as sensory organs, detecting vibrations and air currents. In some species, they also play a role in copulation or defense.
What is the use of the osmeterium?
Osmeteria in insects, particularly swallowtail caterpillars, are primarily used for chemical defense. They are a type of scent gland that releases foul-smelling substances to deter predators, often ants, spiders, and mantids. These secretions can be a warning signal (aposematic) or a direct chemical repellent. They release a mixture of volatile chemicals, including terpenes and aliphatic acids, which deter predators with their unpleasant smell and taste.
What is the use of the exoskeleton?
In insects, the exoskeleton serves as a protective outer layer, a support structure for movement, and a barrier against water loss.
What is the use of the elytra?
In beetles, elytra are the hardened forewings, which primarily serve as protective wing-cases for the membranous hind wings used for flight.
What is the use of two pairs of wings?
What is the use of the pterostigma?
What is the use of the scutellum?
