Question

Answer 1

Most earwigs are elongate, flattened, and are dark brown. Lengths are mostly in the 10-14 mm range. When earwigs have wings (are not agnathous), the hindwings are folded in a complex fashion, so that they fit under the forewings. Earwigs rarely fly.

Copepods are a group of small crustaceans found in the sea and nearly every freshwater habitat. Some copepods are parasitic and attach themselves to fish, sharks, marine mammals, and many kinds of invertebrates such as molluscs, tunicates, or corals

Aphids, also known as greenfly, blackfly or plant lice, are minute plant-feeding insectsAbout 4,000 species of aphids are known, classified in 10 families; of these, around 250 species are serious pests for agriculture and forestry as well as an annoyance for gardeners.
