Mycetina cruciata is a species of beetle belonging to the family Endomychidae. [1] M. cruciata is native to Europe. [1]
Mycetina cruciata beetles measure between 3.8 to 4.5 millimeters in length. Their antennae and legs are black, while the thorax (pronotum) and wing covers (elytra) range from orange to red in color. The beetle gets its name from a black cross-shaped pattern on its wing covers (see Fig. 1 on the right). Often, the crossbar of the cross is broken, and the beetle appears black along the suture with a black spot on each wing cover.
The antennae are segmented, with the 9th antennal segment being conical in shape. The last two segments (antennomeres) are the widest. In male beetles, there is an additional 6th ventral segment.
Other beetles also exhibit similar coloring and cross markings. These include species from the family of fungus beetles (Mycetophagidae) such as the four-spotted fungus beetle (Mycetophagus quadripustulatus), which, however, has a reddish head and reddish legs. Mycetophagus quadriguttatus also belongs to this family and has reddish legs with a less distinct pattern on the elytra (wing covers).
From the family of darkling beetles (Tenebrionidae), the yellow-banded darkling beetle (Diaperis boleti) displays a black band on its yellow to dark orange elytra, although it is notably larger in size. In the same family as the cross-striped cabbage worm beetle, the handsome fungus beetle (Endomychus coccineus) showcases black markings in dot rather than cross formation.
The larvae also feed on fungi and are brown in color. The segmented back features lobe-like projections along the edges of the segments. Running from front to back, there is a light dorsal median stripe. These larvae resemble those of the fungus beetle Aphorista vittata, which, however, is found only in the United States.
Dermestidae are a family of Coleoptera that are commonly referred to as skin beetles. Other common names include larder beetle, hide or leather beetles, carpet beetles, and khapra beetles. There are over 1,800 species described.
The Lymexylidae, also known as ship-timber beetles, are a family of wood-boring beetles. Lymexylidae belong to the suborder Polyphaga and are the sole member of the superfamily Lymexyloidea.
Lordithon lunulatus is a rove beetle. It is a common insect in Europe. The mature adult is about 5 millimetres long. It has distinctively patterned elytra – these are shiny black with pale patches at the outer front corners, and a pale margin at the rear. The thorax is broader at the rear, narrower at the front, shining and reddish brown. The head is long and shiny. The abdomen is largely reddish-brown, but the two rear segments are black. It is covered is pale hairs, and has black setae on its lateral margins. The legs are yellow, and the tarsi are elongated, with five segments on each. The antennae have eleven segments – the first to the fourth and the last are yellow; the others are black.
Mycetophagus punctatus or the hairy fungus beetle is a species of fungus beetle. It can be found in households given the presence of decaying matter and sufficient dampness.
Nicrophorus vestigator is a species of beetle belonging to the family Silphidae.
Nicrophorus tomentosus is a species of burying beetle that was described by Friedrich Weber in 1801. The beetle belongs to the family Silphidae which are carrion beetles. The beetles have sensitive antennae that contain olfactory organs. Thus, the beetle can locate dead animals (carcass), and then as the name suggests, can bury them. However, unlike other burying beetles, N. tomentosus does not completely bury these brood carcasses. They instead dig a shallow hole under the carcass and cover it with leaf litter. Recognition of these beetles can be distinguished by its black color with orange markings on the wing covers (elytra).
Nicrophorus interruptus is a species of burying beetle or sexton beetle belonging to the family Silphidae subfamily Nicrophorinae.
Trox scaber is a beetle of the family Trogidae. The 5 to 8 mm long insect is found worldwide, including in Europe, and lives in bird nests.
Megalodacne is a genus of fungivorous beetles in the family Erotylidae.
Stenopterus rufus is a beetle species of round-necked longhorns belonging to the family Cerambycidae, subfamily Cerambycinae.
Cantharis livida is a species of soldier beetle belonging to the genus Cantharis and the family Cantharidae.
Lagria hirta is a species of beetles in the family Tenebrionidae.
Hippodamia notata is a species of ladybird belonging to the family Coccinellidae.
Cionus hortulanus is a species of weevils belonging to the family Curculionidae, subfamily Curculioninae.
Helophilus obscurus , the Obscure Marsh Fly, is a common species of syrphid fly observed throughout Canada and the northern United States and Rocky Mountains. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae of this genus are associated with wet decaying organic material, particularly accumulations of decaying vegetation in ponds and mud and farmyard manure or silage the larvae of this species are not known.
Mylabris variabilis is a species of blister beetle belonging to the Meloidae family.
Abscondita chinensis, is a species of firefly beetle found in India, China and Sri Lanka.
Sphiximorpha willistoni, or Williston's wasp fly, is a rare species of syrphid fly found in eastern North America. It is a strong wasp mimic. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae in this genus are found in sap runs of trees.
Holostrophus koreanus is a species of polypore fungus beetle in the family Tetratomidae. Being identified in 2022 by Boo Hee Jung and Jinbae Seung, Holostrophus koreanus was described as being found exclusively within the Gangwon province of Korea upon collecting specimens primarily from the fruiting bodies of Polyporales.
Holostrophus toyoshimai is a species of polypore fungus beetle in the family Tetratomidae. Being identified in 2017 by Masahiro Saitȏ and Ondřej Konvička, Holostrophus toyoshimai was identified upon the discovery of five specimens located within central Honshu to which they were identified as a new species.
