Bean thrips

Dark, greyish-black body. Legs are banded light and dark. Both sexes have four wings with numerous fringes surrounding each wing, folded back over the thorax and abdomen when at rest. Forewings banded, two dark and two light grey bands. Antennae have eight segments.

Damage:  Thrips prefer to feed on the flower of the plant; they remove plant cell contents and also feed on the pollen. When infested with thrips the leaves of the plant will appear brownish and/or silvery where they have fed. Adults lay their eggs in the leaf tissue, and population is highest when it is warm and dry.
