Some moths do not feed after emerging from the pupa, and have greatly reduced, vestigial mouthparts or none at all. All but a few adult Lepidoptera lack mandibles (the superfamily known as the mandibulate moths have fully developed mandibles as adults), but also have the remaining mouthparts in the form of an elongated sucking tube, the proboscis.
The larvae – caterpillars – have a toughened (sclerotised) head capsule, chewing mouthparts, and a soft body, that may have hair-like or other projections, three pairs of true legs, and up to five pairs of prolegs. Most caterpillars are herbivores, but a few are carnivores (some eat ants, aphids, or other caterpillars) or detritivores. [2]
What is unusual is that many Hymenoptera have the remaining mouthparts modified to form a proboscis (a "tongue" used to feed on liquids), making them virtually the only insects that normally possess both chewing mouthparts and sucking mouthparts (a few exceptional members of other orders may exhibit this, such as flower-feeding beetles that ...
Piercing-sucking mouthparts have stylets and are used to penetrate solid tissue and then suck up liquid food. Sponging mouthparts are used to sponge and suck liquids, and lack stylets (e.g. most Diptera). Siphoning mouthparts lack stylets and are used to suck liquids and are commonly found among species of Lepidoptera.
The globular compound eyes each have up to 28000 ommatidia and provide sharp color vision; On the forehead there are three ocelli, which can distinguish light from dark, and help with orientation in flight. The two short antennae are tactile receptors. The mouthparts are on the underside of the head and include simple chewing mandibles. [1]
Black flies are the main biting fly in the Upper Peninsula, although people tend to encounter them most near creeks and rivers where their larvae hatch from, appearing mostly in the spring through ...
Head of a horse-fly showing large compound eyes and stout piercing mouthparts A head of a fly, showing the two compound eyes and three simple eyes clearly. Flies have a mobile head with a pair of large compound eyes on the sides of the head, and in most species, three small ocelli on the top. The compound eyes may be close together or widely ...
The simplest and most immediate method is to vacuum up visible cluster flies. Be sure to use a vacuum cleaner with a HEPA filter to trap any eggs or larvae that might be present.
