Explanation of Names
Cosmopterix clandestinella Busck, 1906
Cosmopteryx clandestinella Busck, 1906
See description and figures here.
From Massachusetts and southern Ohio south to Virginia and North Carolina (Hodges, 1978 (1)), Michigan (fig. 273) (2).
There are two generations, the adults have emerged from late May to early June and again in late July and August (Hodges, 1978 (1)). The specimens from Michigan are obviously from the second generation, the mines were collected in August and the adults emerged in May (2).
Dichanthelium clandestinum (L.) Gould (Busck, 1906, as Panicum clandestinum) (Poaceae) (2).
Life Cycle
Leaf miner. The mine is an irregular longitudinal blotch mine with the frass ejected at one end. At maturity the larva cuts a circular piece out of the epidermis of its mine, which it bends lengthwise and uses for a cocoon exactly like the genus Cycloplasis Clemens (formerly in Heliodinidae, unresolved taxonomy) (Busck, 1906) (2).
