Hylaea fasciaria (Linnaeus, 1758)
Description: Wingspan 32-24mm. Adults usually reddish brown with two cross-lines, which are normally edged with white across the forewings. Hindwings paler with a single cross-line.
Key Identification Features:
Flight Period: Mid June to early August.
Status: Widely distributed, recorded from scattered sites throughout all counties. Most of the records are from southern counties, especially Down, which has the largest number of known sites. In recent years it has been recorded more frequently no doubt due to increased fieldwork in many localities. It seems likely that it may be under recorded in Antrim, especially in the conifer plantations in and around the glens, which may have undetected populations.
Ecology: A species normally associated with conifer woodland especially pine. Adults are attracted to light and appear in small numbers in favoured localities. The larvae can be found in September through to May of the following year on Scots Pine Pinus sylvestris, Norway Spruce Picea abies and Douglas Fir Pseudotsuga mensziesii. It overwinters as a larva.
World Distribution: Across Europe to eastern Siberia.
