Males mount other beetles indiscriminately, and homosexual copulation has been known to occur. [24] Anacaena lutescens, a species of hydrophilid beetle, has been observed as reproducing via parthenogenesis. Reproduction by parthenogenesis is relatively uncommon in other types of insects. [25]
Silphidae is a family of beetles that are known commonly as large carrion beetles, carrion beetles or burying beetles. There are two subfamilies: Silphinae and Nicrophorinae. Members of Nicrophorinae are sometimes known as burying beetles or sexton beetles. The number of species is relatively small, at around two hundred.
In April 2012 the guide surpassed 500,000 photos. [7] By October 2014, BugGuide had 30,774 species pages and 48,572 total pages, with over 808,718 images submitted by more than 27,846 contributors. [8] On 22 September 2014, BugGuide surpassed 1,000,000 pages (most of which are photographs). [9]
The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal species; [2] new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species.
Larvae of the black carpet beetle Attagenus megatoma may grow up to 1 ⁄ 2 inch (13 mm) and be yellow to brown in color. Other types of carpet beetle are regularly 1 ⁄ 4 to 1 inch (6.4 to 25.4 millimetres) long and covered with dark setae. Certain species have distinctive tufts of setae extending from their posterior end.
The rove beetles are a family (Staphylinidae) of beetles, [2] primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is one of the largest families in the beetle order, and one of the largest families of ...
Hydrophiloidea, known as water scavenger beetles, is a superfamily of beetles. Until recently it included only a single family, the Hydrophilidae (water scavenger beetles), but several of the subfamilies have been removed and raised to family rank. [1] Hydrophiliidae remains by far the largest member of the group, with nearly 3,000 described ...
A water beetle is a generalized name for any beetle that is adapted to living in water at any point in its life cycle. Most water beetles can only live in fresh water, with a few marine species that live in the intertidal zone or littoral zone. There are approximately 2000 species of true water beetles native to lands throughout the world. [1]
