The pupae are
ovoid and remain firmly attached to rocks that are regularly washed or splashed by water, using paired adhesion disks rather than the more typical suction disks. Upon emergence, adults resemble delicate
craneflies, possessing elongated antennae and wings marked by a distinctive network of fissures and folds, somewhat evocative of broken safety glass. Adult net-winged midges often suspend themselves from vegetation similar to
scorpion flies or cling to moist rock faces near the streams and rivers inhabited by their larvae. They obtain food by scraping
diatoms and other microorganisms from surfaces. In numerous lineages, females exhibit predatory behaviour, seizing
mayflies and other small insects with specialized hind
tarsi. ==References==
