Thrips

COMMON THKUPS Family Thripidae Identification: Ovipositor usually well developed, curved downward. FW pointed apically. Body somewhat flattened. Antennae 6- to 9-segmented, sensory areas (sensoria) on segments 3 and 4 conelike or fingerlike and projecting.

Thripids make up the bulk of the Terebrantia, and nearly all species are plant feeders; some are serious pests of cultivated plants. Most are 1.5 mm. or less.

HETEROTHRIPIDS Family Heterothripidae Not illus.

Identification: Similar to Thripidae, but antennae 9-segmented, and 3rd segment with an apical band of small blisterlike sensoria.

Seldom encountered in our area. One fairly common species feeds in the flowers of jack-in-the-pulpit.
