The beetles' glands store enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. In some cases this is enough to kill a predator. [6] The main component of the beetle spray is 1,4-benzoquinone, an irritant to the eyes and the respiratory system of vertebrates.
Cotinis nitida, commonly known as the green June beetle, June bug or June beetle, [1] is a beetle of the family Scarabaeidae. It is found in the eastern United States and Canada, where it is most abundant in the South. It is sometimes confused with the related southwestern species figeater beetle Cotinis mutabilis, which is less destructive.
Many other beetles, including ladybirds, blister beetles, and lycid beetles secrete distasteful or toxic substances to make them unpalatable or poisonous, and are often aposematic, where bright or contrasting coloration warn off predators; many beetles and other insects mimic these chemically protected species.
If you or a loved one is experiencing an allergic reaction after coming into contact with a poisonous plant, you can call Texas Poison Control at (800) 222-1222 to seek help.
The probability of a beetle guarding is dependent on both the sex ratio and the size of an individual. A larger beetle is more likely to guard than a smaller beetle because smaller beetles require more energy to maintain guarding and are thus unable to compete with larger beetles, so the smaller beetles get little marginal benefit by guarding.
Female margined blister beetle pursued by multiple males. Cantharidin, a poisonous chemical that causes blistering of the skin, is secreted as a defensive agent. It is used medically to remove warts [2] and is collected for this purpose from species of the genera Mylabris and Lytta, especially Lytta vesicatoria, better known as "Spanish fly".
Cotinis mutabilis, also known as the figeater beetle (also green fruit beetle or fig beetle), is a member of the scarab beetle family. It belongs to the subfamily Cetoniinae , comprising a group of beetles commonly called flower chafers since many of them feed on pollen, nectar, or petals. [ 1 ]
European rhinoceros beetle European rhinoceros beetle – three stages from larva to adult: larva (back), pupa (center), and imago (front). The Dynastinae are among the largest of beetles, reaching more than 15 centimetres (6 inches) in length, but are completely harmless to humans because they cannot bite or sting.
