Insects Control & Tree Diseases


tree care insect control The Winter Moth (Operophtera brumata) is a moth of the family Geometridae. It is an abundant species of Europe and the Near East and one of very few Lepidoptera of temperate regions in which the adults are active in the depth of winter.

The female of this species is virtually wingless and cannot fly, but the male is fully winged and flies strongly. Its wingspan is 28–33 mm with alternating pale buff and darker brown fascia on the forewings and a similar pattern, but much paler, on the hindwings. The adults are active at night throughout the winter from October to February[1]. Males are strictly nocturnal and attracted to light and females.

After mating, females lay their eggs in tree bark crevices or in other sheltered locations, and all adults die. The eggs hatch in the spring when temperatures average around 13°C (55°F). After hatching, the young larvae crawl up tree trunks and produce silken thread that can carry them in the wind to new areas. This dispersal method, called "ballooning," is common among defoliators.
