SubfamilyConiopteryginae

Genus Coniopteryx (17 spp.)

Genus Conwentzia (4 spp.)

Genus Parasemidalis (1 sp.)

Genus Semidalis (11 spp.)

Size

body length 2.5-5 mm

Identification

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)

Range

both subfamilies occur worldwide and throughout NA

Habitat

predominantly arboreal

Season

most active at dawn and dusk in spring and fall

Food

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

Remarks

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
