Macrosaccus robiniella (Clemens, 1859)
< back | next >
blotch mine under the elaf

 

Food Plant: Robinia spp

Mine: trivoltine June-October

Notes: A native of North America accidentally introduced into Europe in 1983. Forms white oval blotch mines on the leaf underside, which do not cross the midrib. Many mines may be formed on a leaf and they may merge (up to 15 larvae may be found in a mine as a result). Please note that the immature mines of this species can resemble those of Parectopa robinella. (Plant pers.comm.)
