The harlequin beetle (Acrocinus longimanus) is a large and distinctly colored species of longhorn beetle from the Neotropics and the only member of the genus Acrocinus. [1]It is given its English name because of the elaborate pattern of black, orange-red and greenish-yellow markings in both sexes; [1] [2] despite this the beetle is quite well-camouflaged when perched on a lichen or fungus ...
The adult beetle can be 11 to 28 mm (0.43 to 1.10 in) long, and it has a W-shaped third stripe on the elytra. The antennae of both sexes are dark brown to black. The male's antennae are two-thirds its body length, and the female's are one-half. The legs are reddish brown.
Adult drugstore beetles are between 2.5 and 3.5 millimetres (3 ⁄ 32 and 1 ⁄ 8 in) long and have a reddish-brown colour with a cylindrical body. Larvae are habitually curled. The pupa is proportionally more slender than that of the cigarette beetle. [1] Drugstore beetle on human fingertip Ventral side of drugstore beetle
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns (whose larvae are often referred to as roundheaded borers), are a large family of beetles, with over 35,000 species described. [2] Most species are characterized by antennae as long as or longer than the beetle's body.
The adult is 12–14 mm (1/2-5/8") in length, [4] [page needed] and has fairly long legs. The mandibles give these attractive insects a ferocious appearance. While tiger beetles are voracious predators of small arthropods, they do not bite humans unless handled.
Members of Ancyronyx superficially resemble spiders and are aquatic, hence their common name, "spider water beetles". They are typically very small, with an average body length (without legs) of 1 to 2 mm (0.039 to 0.079 in). They are characterized by extremely long legs (longer than the body length). [4]

The saliva contains enzymes that digest the tissues they swallow. This process is generally referred to as extraoral digestion. [8] The saliva is commonly effective at killing prey substantially larger than the bug itself. The legs of some Reduviidae have areas covered in tiny hairs that aid in holding onto their prey while they feed.
