Recognizing thrips:

Thrips are the smallest winged insects, though you can hardly see their wings. With a microscope you can see the wings and you can see that they have some kind of fringe at the back. This is characteristic for thrips. They may occur in many plant species, on the leaves and / or flowers. Some species pupate on or just in the upper part of the soil. All species lay eggs in the leaf tissue, so nearly invisible. The young stages hatch from the eggs and move around over the plant. Young stages are generally light in color, yellow to white; adult thrips are very different in color from light yellow to almost black. Most species are very mobile. Especially in the summer thrips can develop very quickly.

Thrips are plant sap suckers. They scrape the leaves, so not really puncturing the plant cells. The damage is usually visible as silver-gray spots on the leaves containing black dots, the excrement of the thrips. Feeding damage from thripses such as blemishes and distortion occurs in flowers and buds. Several thrips species can transmit viruses which makes them even more feared among growers.

Thrips can be roughly divided into two groups: leaf and flower-dwelling dwelling species. The leaf dwelling ones mainly suck from leaf tissue and do not feed on pollen; flower dwelling species can feed themselves on plant tissue but also on pollen.
