What are the major characteristics of insects that belong to Coleoptera?

Coleoptera are holometabolus, thus possess distinct egg, larval, pupal, and adult stages. Beyond that it is difficult to make broad generalizations about the aquatic Coleoptera. Most adults and larvae are substrate dwellers, but some are efficient swimmers (e.g., larval and adult Dytiscidae and Hydrophilidae).

What is the defining characteristic of Coleoptera?

Coleoptera – beetles and weevils. The forewings of beetles are heavily sclerotised and form protective covers over the hind wings. The forewings are called elytra and Coleoptera means ‘sheath wings’ i.e. the hard sheath-like elytra over the soft hind wings.

How Coleoptera are different from the other insect?

1. Chewing mouthparts (sometimes located at the tip of a beak or snout)
2. Front wings (elytra) are hard and serve as covers for the hind wings; meet in a line down the middle of the back.
3. Hind wings large, membranous, folded beneath the elytra.
4. Tarsi 2- to 5-segmented.

How many species are there in Coleoptera?

Beetles (Order Coleoptera) are known to include some 350,000 described species. In the United States, there are nearly 30,000 kinds of beetles known.

What type of legs do Coleoptera have?

Most beetles have running or crawling legs, but many have rake-like forelegs used to dig, flattened or hairy legs for swimming, or enlarged hind legs for jumping. The tarsi are important for identification, because beetles have a variable number of tarsal segments on each leg.

Why is Coleoptera the largest order of insects?

Life History & Ecology Coleoptera (beetles and weevils) is the largest order in the class Insecta. As adults, most beetles have a hard, dense exoskeleton that covers and protects most of their body surface. The front wings, known as elytra, are just as hard as the rest of the exoskeleton.

The adults are easily recognized by their two pairs of narrow, transparent wings, sloping thorax, and long, usually slender body; the abdomen is almost always longer than any of the wings.
