14.012 Bucculatrix bechsteinella (Hawthorn Tuft)
ws: 7-9mm; May, (Sep); leaf mine hawthorn (Crataegus spp), pear (Pyrus communis); widespread and common in scrub, hedgerows and woodland margins.
ID: Appears very similar to B.albedinella. Separated in key in MBGBI2 by presence (albedinella) or absence (bechsteinella) of a blackish apical streak in forewing.
The date of §1, 03/08/2010, suggests that this is a second generation individual. B.albedinella is univoltine in June. B.bechsteinella is usually univoltine from May to early June but is said to have a second generation in favourable years (in September). Coincidentally, §2 was trapped exactly one year later (03/08/2011) and §4 was also trapped in August. It does therefore seem that the second generation occurs in August in Essex.
