How do I recognize thrips?

Thrips are so small that you have to look carefully to find them. Adult thrips have an elongated body with ragged wings. They are about 1-2 mm in size and often yellow, brown or black in color. These little creatures can be found in the flowers or on the leaves of many different plants.

Trip's egg

Adult thrips provide a sheltered spot for their eggs. They gnaw a hole and lay the egg in leaves, petals or in the stem. This means the eggs are well protected against natural enemies. The eggs are very small and cannot be clearly seen with the naked eye.
