b'Subterranean caterpillar | AGROTIS SPECIESSubterranean caterpillars are round, grey, twisted caterpillars, the size of which varies from a few millimeters to 3 centimeters. They can be found all the year round. They are caterpillars of different kinds of owl butterflies. Most species have one generation per year. If the caterpillars are still small, they live aboveground on young leaf green. However, they pass on rather quickly to a way of living underground. They eat from roots and different underground young parts of plant. Besides, they eat from the aboveground parts of plant during the night time. Subterranean caterpillars can often be easily found in the soil, because they take along parts of plant to their places of shelter.Leather jacket | TIPULA SPECIESLeather jackets are the larvae of the daddy longlegs.This insect is present especially in ploughed up grassland.
