P. vindex adults are hard-bodied beetles which range from approximately 11-22 millimeters (0.4-0.9 inches) in length. They are relatively bulky and oblong. These beetles are sexually dimorphic; the males can be identified by their iridescent elytra and a large horn on their heads while females have slightly less vibrant shells and lack horns.
Beetles have mouthparts like those of grasshoppers. The mandibles appear as large pincers on the front of some beetles. The mandibles are a pair of hard, often tooth-like structures that move horizontally to grasp, crush, or cut food or enemies (see defence, below). Two pairs of finger-like appendages, the maxillary and labial palpi, are found ...
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.
The beetles cannot be mounted normally using stainless steel pins; rather, a hole must be drilled in the shell for the pin to be inserted. [8] A jigsaw-like layering of multiple scales of different sizes, ranging from microscopic to visible sizes, provides exceptional mechanical strength to the beetle's appendages.
The musk beetle (Aromia moschata) is a Eurasian species of longhorn beetle belonging to the subfamily Cerambycinae, tribe Callichromatini. Its name comes from the delicate musky smell it emits when menaced. The beetle has a shell with an iridescence tone that changes with the angle of view. It has a hard shell around the thorax with hard sharp ...

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.
The walnut twig beetle's hard shell covers two wings, and because the beetle can fly, G. morbida is reliant on the walnut twig beetle to be spread across distances, making the fungus entomochoric, or completely dependent upon the walnut twig beetle for dispersal, and only found in habitats containing the beetle.
