Dermolepida albohirtum, the cane beetle, is a native Australian beetle and a pest of sugarcane. Adult beetles eat the leaves of sugarcane, but greater damage is done by their larvae hatching underground and eating the roots, which either kills or stunts the growth of the plant. [ 1 ]
In most small gardens, the adult beetles are minor pests that do little damage; however, they can swarm on soft or damaged fruit and have been known to eat an entire garden grape or fig crop. [1] They are not considered to be an important pest because they do not damage lawns as larvae and trees as much as June beetles or Japanese beetles.
The beetle is able to survive by collecting water on its bumpy back surface from early morning fogs. To drink water, the S. gracilipes stands on a small ridge of sand using its long, spindly legs. Facing into the breeze, with its body angled at 45°, the beetle catches fog droplets on its hardened wings, or elytra. Its head faces upwind, and ...
Small red and orange insects with spots have been giving ladybugs a bad rap for the havoc they've been causing.
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.
Dung beetles do not necessarily have to eat or drink anything else, because the dung provides all the necessary nutrients. [citation needed] Most dung beetles search for dung using their sensitive sense of smell. Some smaller species simply attach themselves to the dung-providers to wait for the dung.
Odontotaenius disjunctus Image of Odontotaenius disjunctus (Illiger, 1800), collected from a wood shed in Haddock, GA. Scale bar represents 1 cm. [1] Odontotaenius disjunctus, the patent-leather beetle or horned passalus, is a saproxylic beetle in the family Passalidae (bess beetles) which can grow to just over an inch-and-a-half long, weigh 1-2 grams and are capable of pulling 50 times their ...
The yellow mealworm beetle can be differentiated from other beetles, due to the linear grooves that are evenly divided and run along the abdomen. The beetle has only four tarsal segments on its hind legs. Most ground beetles, which are similar in size to Tenebrio molitor, have five tarsal segments. [4]
