Ulmus minor, Duin en Kruidberg: excision for the initial cases
detail
juvenile mine, very young case
mine
Oviposition generally in a vein axil. From there a short, relatively wide corridor is made that quickly widens into an elliptic blotch. Much of the frass is ejected through the hole that the larva has made to bore itself into the leaf (in C. badiipennella, on the same hostplant, the frass remains within the mine (Emmet, Langmaid, Bland ao, 1996a]). This blotch is excised to make the juvenile case. The full grown larva lives in a brown spathulate leaf case of 9-11.5 mm; its rear end is bivalved. Mouth angle 0°-20°; just behind the mouth the case shows a conspicuous bend.
