Scydosella is a genus of beetles that consists of only one species Scydosella musawasensis. The species is regarded as the smallest free-living insect, as well as the smallest beetle. [ 1 ] They are among featherwing beetles , named because of their feather-like spiny wings.
This family contains the smallest of all beetles, [3] with a length when fully grown of 0.3–4.0 millimetres (0.01–0.16 in). [2] The weight is approximately 0.4 milligrams. [4] Ptillid wings are feathery due to the much higher effective viscosity of air at small body sizes, which makes normal insect wings much less efficient.
Many species of leaf beetles, longhorn beetles, and weevils are very host-specific, feeding on only a single species of plant. Ground beetles and rove beetles ( Staphylinidae ), among others, are primarily carnivorous and catch and consume many other arthropods and small prey, such as earthworms and snails.
The drugstore beetle is a reddish brown, small beetle ranging from about 1/10 to 1/7 inches (2.25 mm to 3.5 mm) long. [11] When viewed from above, the beetle has an oval shape with a rounded head and dorsal plate that’s bent forward. Adults have serrated antennae ending in three final segments that are more enlarged and distinct.
The small, orange beetle belongs to same family as ladybugs but differs in a few key ways.
Coccinellidae (/ ˌ k ɒ k s ɪ ˈ n ɛ l ɪ d iː /) [3] is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in the United Kingdom; "lady" refers to mother Mary. Entomologists use the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described ...
Even the soldier beetle’s thorax is similar to that of many firefly species. Adult bugs feed on nectar, pollen, and other smaller insects, while their larvae feed on snails and other small ...
Hydraenidae is a family of very small aquatic beetles, sometimes called "Minute moss beetles", with a worldwide distribution.They are around 0.8 to 3.3 mm in length. The adults store air on the underside of the body as well as beneath the elytra which allows them to crawl underwater, often on the underside of the water surface tension, though they cannot swim.
