Once metamorphosis is complete, the insect sheds its pupal skin and undergoes a period of hibernation as an adult beetle until the dry season ends. [2] When the rains begin, the beetle breaks open its cocoon, locates a mate, and the entire life cycle starts over again. The adult beetles feed on materials rich in sugar, especially tree sap and ...
Nearly all of the 500-odd species are tropical; species found in North America are notable for their size, ranging from 20 to 43 mm, for having a single "horn" on the head, and for a form of social behavior unusual among beetles. Bodies are elongate-cylindrical and black overall; ventral surfaces may be covered with yellow setae.
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.
What they look like: Chiggers, a type of small mite, typically leave clusters of bites that are often very itchy. In many cases, chigger bites appear as small, red and itchy bumps. Sometimes, they ...
Female M. melolontha Beetle. Adults appear at the end of April or in May and live for about five to seven weeks. After about two weeks, the female begins laying eggs, which she buries about 10 to 20 cm deep in the earth. She may do this several times until she has laid between 60 and 80 eggs. Most typically, the female beetle lays its eggs in ...
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.
Meloe is a genus of blister beetles commonly referred to as oil beetles. [1] The name derives from their defensive strategy: when threatened they release oily droplets of hemolymph from their joints (legs, neck, and antennae). This fluid is bright orange and contains cantharidin, a poisonous chemical compound. Wiping the chemical on skin can ...
Chrysochus auratus, more commonly known as the dogbane beetle, is a leaf beetle primarily found in the eastern United States. The beetle is approximately 8 to 11 mm in length, and possesses an oblong and convex shape. This beetle has two pairs of wings, one of which is a pair of copper colored elytra.
