The pronotal is a protective hard shell that encompasses the beetle's thorax region; the elytral are the beetle's wings that rest on its side. When threatened, these beetles will begin to release small excretions through both of these glands. These secretions have been found to include the toxic cardenolide molecules.
While all beetles have flight muscles that work antagonistically – when one shortens, the other stretches – only a small percentage are functional. In addition, the beetles with flight potential have a short flight period. The arrested development of the flight muscles, causing the inability to fly, may be an evolutionary choice.
Elateridae or click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae and Eucnemidae, which are also capable of clicking) are a family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815.
They are typically small beetles, with some very small species only half a millimeter in length. Scydmaenids typically live in leaf litter and rotting logs in forests, preferring moist habitats. A number of types are known to feed on oribatid mites, using "hole scraping" and "cutting" techniques to get through the mite's hard shells.
Clambidae is a family of beetles. They are known commonly as the minute beetles [2] or the fringe-winged beetles. [3] They are found worldwide on every continent except Antarctica. [2] These are tiny beetles with bodies measuring 0.7 to 2mm in length. They are flattened to convex in shape and some can roll into a ball.

The ten-lined June beetle (Polyphylla decemlineata), also known as the watermelon beetle, is a scarab beetle found in the western United States and Canada. The adults are attracted to light and feed on foliage .
When viewed from above, most beetles appear to have three clear sections, but this is deceptive: on the beetle's upper surface, the middle section is a hard plate called the pronotum, which is only the front part of the thorax; the back part of the thorax is concealed by the beetle's wings. This further segmentation is usually best seen on the ...
