BARKFLIES

Immaculate Birdlouse (3-4mm) has fairly clear wings and a greenish abdomen. It lives on a variety of deciduous and evergreen trees, usually on branches (not trunks) from June to October. This species also inhabits leaf litter and log piles.

F-winged Barklouse has dark markings on its wings and a 'neck' typical of barkflies. It inhabits a wide range of trees and shrubs and can be found throughout the year but rarer during the winter months.

Yellow Barkfly is a small (3 mm) light-yellow insect with well marked wings. Found active on a wide range of trees and bushes from June until October. It overwinters in leaf litter.

Ectopsocus briggsi is small (1.5–2mm) with dark spots on forewings. The wings are always longer than abdomen. This is one of the commonest species in the United Kingdom. There are several similar species which can only be separated by examining their genitalia with a microscope, therefore this was recorded as Ectopsocus briggsi agg. (briggsi/petersi/meridionalis). Mainly seen during summer when feeding on fungal spores and microflora on leaf surfaces.
