Grain moth

Sitotroga cerealella

The grain moth is one of the main pests in the grain industry. The larvae of the moth damage the grain crop from the inside out and only leave the grain as fully developed adults. However, it not only develops in stored grain, but can also attack grain crops on the stalk and is thus introduced unnoticed into warehouses. The speed of development depends on the temperature and is between 25 days and 4 months. Wingspan of the moth up to 19 mm, forewings clay yellow with black spots. Hind wings unicolored, grey. Caterpillars first yellowish red, then white, up to 6 mm long, cylindrical.
