The following account is summarized from Kuznetzov (1978)Kuznetzov (1978):
Kuznetzov, V. I. 1978. Family Tortricidae (Olethreutidae, Cochylidae), pp. 193-680. In : Medvedev, G. S. (ed.), Keys to the insects of the European part of the USSR 4(1). Opred. Faune SSSR (117): 193-686 [In Russian; English version published for the National Science Foundation (Washington, DC) by Amerind Publishing Co.].. Detailed accounts of larval chaetotaxychaetotaxy:
the arrangement of setae (in reference to Lepidoptera larvae), often depicted on a "setal map"
have not been published.
Young larvae are yellowish-green with black heads. Mature larvae have the head dark amber brown; prothoracic shieldprothoracic shield:
a sclerotized plate on the dorsal surface of the prothorax
, body, and legs pale green.
Eulia ministrana is unlikely to be confused with any other species of tortricid. It is a highly distinctive species in both forewing pattern and genitalia.
Despite its widespread occurrence, very little is published in the way of life history notes for Eulia ministrana. There is a single generation per year, with adults peaking in activity in mid-June, regardless of hemisphere. In North America, adults fly as early as late May in Washington and Alaska and as late as mid-July in Nova Scotia and New Brunswick. Females lay eggs single or in groups of up to 20 on the leaves the host plant. Larvae feed inside rolled leaves. Overwintering occurs as a mature larva with pupation occurring in the spring (Kuznetzov 1978Kuznetzov 1978:
Kuznetzov, V. I. 1978. Family Tortricidae (Olethreutidae, Cochylidae), pp. 193-680. In : Medvedev, G. S. (ed.), Keys to the insects of the European part of the USSR 4(1). Opred. Faune SSSR (117): 193-686 [In Russian; English version published for the National Science Foundation (Washington, DC) by Amerind Publishing Co.].; Zrerev & Kozlov 2020).
Eulia ministrana is a highly polyphagous species and has been recorded feeding on many different plants.

In North America, it has been recorded from Alaska to Oregon and east to Maine and Nova Scotia and south through the Appalachians to Tennessee and North Carolina. There is no clear genetic separation between Palearctic and Nearctic populations (Gilligan et al. 2020bGilligan et al. 2020b: LinksAdditional photos and a distribution map of this species in North America are available at Moth Photographers Group. |
