Entomobryidae

(Redirected from Orchesellinae)

Entomobryidae, sometimes called "slender springtails", is a family of springtails characterised by having an enlarged fourth abdominal segment and a well-developed furcula. Species in this family may be heavily scaled and can be very colourful. The scale-less Entomobryidae are commonly caught in pitfall traps around the planet, and also occur in canopy faunas high up in trees (notably Entomobrya nivalis, very common throughout Europe if not the Northern Hemisphere). There are more than 1700 described species in Entomobryidae.[1][2][3][4]

Description

edit

This family has a reduced prothorax that lacks setae. The antennae are longer than the head diagonal. A mandibular plate is present. The abdominal segments are not fused. The body has trichobothria and thick clavate setae, and often scales as well. The dens is longer than the manubrium, tapering and annulated. The dentes are roughly parallel and distally curved. The mucro is small and has one or two teeth.[5]

In more general terms, Entomobryidae tend to be relatively large springtails, reaching 2 mm or more. They may have stripes, bands or streaks of blue, red or purple. Some species are all blue or all white, the latter tending to also have reduced ocelli. Cave-dwelling species have long appendages and the claws are often modified.[5]

Ecology

edit

On humid mornings, many entomobryid species climb herbaceous plants to feed on pollen and the spores of fungi.[6]

Entomobryids have been found in brood galleries of bark beetles, where they are presumed to feed on fungi or act as saprophages.[7]

Some species live in intertidal habitats.[8]

Springtails of this family are prey for a range of predators, including various ground beetles, the shore bug Saldula saltatoria, lady beetle larvae,[9] ants and crab spiders.[6]
