Genus Conwentzia (4 spp.)
Genus Parasemidalis (1 sp.)
Genus Semidalis (11 spp.)
body length 2.5-5 mm
Adults covered with white waxy powder which gives a granulated appearance to the surface when viewed close-up; wings whitish with reduced venation, and held tent-like over abdomen at rest; antennae long and slender; mouthparts moderately long and beak-like; legs relatively long, especially hindlegs.
Wing venation of Semidalis:
Larva: five simple eyes on each side of head, and needle-like jaws
Keys to NA subfamilies & genera in(2); key to FL genera
Genus-level identification usually requires seeing the venation of both fore- and hind wings (György Sziráki, pers. comm. to =v=, 15.x.2011)
both subfamilies occur worldwide and throughout NA
predominantly arboreal
most active at dawn and dusk in spring and fall
adults and larvae feed on aphids, mealybugs, spider mites, scale insects, whiteflies, and other soft-bodied arthropods; adults have been reported to feed on other substances, e.g. honeydew, scale secretions, and honey water(2)
Life Cycle
adults flutter slowly among plants and usually lay single eggs on bark or leaves; two generations per year; overwinters as a larva
easily overlooked due to small size and crepuscular habits; may be more economically important as predators of homopteran pests than previously realized
See Also
adults superficially similar to whiteflies (Aleyrodidae) but have longer legs (esp. the hindlegs), longer antennae, longer beak-like mouthparts, and wings held tent-like at a more steep angle over the abdomen at rest
