Species undescribed-species-on-milkweed (Contarinia undescribed-species-on-milkweed)
Range
NY (1)
Season
Adults were reared in August from larvae collected in July, so there is probably more than one generation per year (1).
Food
Known from swamp milkweed (Asclepias incarnata) (1).
Remarks
Larvae develop in distorted milkweed leaves. The gall was described as a swollen midrib fold in Felt (1940) (2) but as a rolled leaf in Felt's unpublished notebook (1).
