Stethaspis Prasinus
''Stethaspis'' is a genus of beetles in the family Scarabaeidae, subfamily Melolonthinae. Description Like other Melolonthinae, adult ''Stethaspis'' are oval and robust in shape. The antennae are relatively short and have the last few segments flattened and finger-like. The elytra leave the end of the abdomen exposed. ''Stethaspis'' are green in colour and range from 13 to 24 mm in length. Larvae are creamy white with a prominent head, relatively large legs and a darkened posterior end (this darkening is due to the gut contents showing through the body wall). The body is curled up into a C-shape. When mature, ''Stethaspis'' larvae can be up to 45 mm long. Ecology Similar to other melolonthines, ''Stethaspis'' beetles feed on plant foliage as adults and plant roots as larvae. Adults are known to damage Douglas fir. Larvae of ''S. longicornis'' are eaten by Polynesian rats. Additionally, ''Stethaspis'' larvae are potential hosts for the introduced scoliid wasp '' Radumeris ...

Scarabaeidae Genera
The family Scarabaeidae, as currently defined, consists of over 35,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change. Several groups formerly treated as subfamilies have been elevated to family rank (e.g., Bolboceratidae, Geotrupidae, Glaresidae, Glaphyridae, Hybosoridae, Ochodaeidae, and Pleocomidae), and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Catalog of Life (2023). Description Scarabs are stout-bodied beetles; most are brown or black in colour, but many, generally species that are diurnally active, have bright metallic colours, measuring between . The antennae of most species superficially seem to be knobbed (capitate), but the several segments comprising the head of the antenna are, as a rule, lamellate: they extend laterally into plates called lamellae that they usually keep compressed into a ball.

Ectoparasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of taxa across the insect superorder Endopterygota, whose complete metamorphosis may have pre-adapted them for a split lifestyle, with parasitoid larvae a ...

Beetle
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ...
