Phenological cycle

Adults appear in summer, flying from June to September. They reproduce and make the same day on the aciculas of the trees, forming a cylinder of eggs around the blade that the female protects by placing scales of her own body. Adults are difficult to find since they have a very short life (2-3 days).

The eggs hatch at 30 days and the larvae begin to feed on the shoots. They have gregarious character, forming pockets in the sunniest parts of the tree, to protect themselves from the winter cold, normally from the month of October. At the end of winter, and after passing through five larval stages, they descend from the trees in procession to bury themselves in the ground to a depth of up to 20 cm and pupate inside a silk cocoon.

Next summer will appear the new generation of adults from these pupae, completing the cycle. In exceptional cases, pupae can enter diapause, remaining in that state for a maximum of four years when the conditions are not adequate.
