Ectoedemia (Ectoedemia) subbimaculella (Haworth)

Biology. Hostplants: Quercus robur L., Q. petraea (Matt.) Liebl. , Q. pyrenaica Willd. , Quercus pubescens Willd. , in Hungary, Moravia and Bosnia found on Q. cerris L. Rarely on Q. rubra L. Univoltine , larvae from September until November, adults flying from May to July.

Distribution. Ireland: Shackleton 1977; Estonia: Kerppola 1994; Latvia: Savenkov 1989; Lithuania: Diškus 2003; Spain, Van Nieukerken et al. 2004a; Greece: Laštůvka and Laštůvka 1998. Here recorded new for San Marino and Tunisia.

Remarks. Many records of adults that haven’t been reared are uncertain, males cannot be identified when not reared, unless by DNA analysis. Th e population on Quercus cerris in Hungary and southern Moravia deviates from sympatric populations on other oaks: larvae were found much earlier, usually in the first half of September (larvae of E. subbimaculella occur more than one month later on Quercus robur and Q. petraea growing together with Q. cerris ).

Material. Hungary: 2♁, 4♀, Gánt, 18.IX.2004, larvae on Quercus cerris , e.l.
