Feniseca tarquinius, the harvester, is a butterfly of the family Lycaenidae, and the only member of the monotypic genus Feniseca. It is found in eastern North America.

This butterfly is the only carnivorous (i.e., insectivorous) butterfly in North America (there are a handful of carnivorous moths, for example Fulgoraecia exigua).[https://bugguide.net/node/view/462023 Bugguide.net. Carnivorous Lepidoptera] The larvae feed on various aphids, such as Neoprociphilus, Pemphigus, Prociphilus, and Schizoneura.

It is found in early spring until fall and is generally scarce. It lives in wooded areas near streams close to alders.Kaufman, Kenn; Brock, Jim P. (2003). "Coppers and Harvester". Kaufman Field Guide to Butterflies of North America. Houghton Mifflin Books. pp. 80–81. {{ISBN|978-0-618-76826-4}}.

The wingspan is 23–32 mm.[http://www.cbif.gc.ca/spp_pages/butterflies/species/Harvester_e.php Harvester], Butterflies of Canada

Another butterfly which is possibly carnivorous is Celastrina serotina. It feeds on galls on black cherry and possibly also on the eriophid mites that make the galls.[https://www.researchgate.net/publication/270161386_Celastrina_serotina_Lycaenidae_Polyommatinae_a_New_Butterfly_Species_from_the_Northeastern_United_States_and_Eastern_Canada.
