Orthosia cruda (Denis & Schiff., 1775)
Description: Wingspan 28-32 mm. Adults are variable in colour. The forewings vary from light greyish brown to reddish brown usually with darker stigmata and small dark coloured dots towards the costa. The apex is well rounded. The subterminal line is normally a series of small pale-coloured dots. Hindwings are whitish brown with darker veining.
Key Identification Features:
Flight Period: Early March to the beginning of May.
Status: Common and recorded from all counties. Most frequently encountered in sites around the Lough Neagh basin although this may be because of frequent trapping in the early part of the year. Apparently absent from most of the north and west, which might be due to its early flight period and reduced trapping at this time of the year.
Ecology: An early spring species found mainly in woodland and occasionally suburban gardens. Adults come frequently to light and will also feed at willow Salix spp. catkins.
World Distribution: Throughout Europe as far north as Sweden and south to Portugal.
