Thrips

Thrips (Thysanoptera) are also known as thunder flies, thunder bugs, storm flies, thunder blights, storm bugs, corn flies and corn lice. Their legs usually end in two tarsal segments with a bladder-like structure and their four very wings have ciliated fringes on the edges.

In Denmark, there are more than 100 different thrips species and it is difficult to distinguish between them. Most are small, less than 2 mm long, black or brownish. The head of a thrip is bent downward and backward, and its mouth parts form a short, cone-shaped tube enclosing three stylets used to pierce the cell wall of tissues.
