Scientific name: Dendrolimus pini
June to September. Thought to be an immigrant from mainland Europe but also suspected to have been introduced via imported trees and timber.
This species can be quite distinctive although it is also very variable in its colouring. The forewings have three cross-lines; a high cross-line curving around a white spot, a central scalloped cross-line and a lower cross-line which is irregular and jagged. The wings can be predominantly warm reddish-brown but also commonly with areas of grey and brown.
The adults are incapable of feeding. They fly at night and are attracted to light. In mainland Europe they overwinter as part-grown larvae on the ground among fallen tree needles or moss.
