The adults drink dew and nectar. The larvae prey on or become parasites of gastropods (slugs and snails). The occasional sciomyzid attacks snail eggs or fingernail clams. [3] Very little is known about the complete life cycle of these flies but most of the known larvae are semi-aquatic and some are aquatic. Other species have terrestrial larvae.
The adults of Coremacera marginata grow up to 7–10 millimetres (0.28–0.39 in) long. These flies have a slender, dark greyish body. The prominent eyes are reddish. The brown-yellowish antennae are forward-pointing, with a hairy 3rd segment and a whitish arista. The dark grey wings are mottled with greyish spots.
Wings may have evolved from appendages on the sides of existing limbs, which already had nerves, joints, and muscles used for other purposes. These may initially have been used for sailing on water, or to slow the rate of descent when gliding. Two insect groups, the dragonflies and the mayflies, have flight muscles attached directly to the ...
Adult snakeflies are easily distinguished from similar insects by having an elongated prothorax but not the modified forelegs of the mantis-flies. Most species are between 15 and 30 mm (0.6 and 1.2 in) in length. The head is long and flattened, and heavily sclerotised; it may be broad or taper at the back, but is very mobile. The mouthparts are ...

This finally results in a slow death by starvation. The rosy wolf snail is a hermaphrodite and is oviparous. [3] The courtship rituals for the snail begin with one following the trail of another snail. The pursuing snail then mounts the rear side of the shell of the snail it was following.
The snail feeds on a variety of plants, including economically important crops such as bananas, lettuce, peanuts, and peas. [5] There are also possible public health ramifications of the spread of the snail as an invasive species: it is a carrier of the parasitic rat lungworm, which causes angiostrongyliasis, which in turn is the most common cause of the eosinophilic meningitis or eosinophilic ...
