Description

Calycomyza eupatoriphaga Eiseman & Lonsdale

Material examined. MASSACHUSETTS: Franklin Co., Sunderland, 42.467340, −72.583361, 30.ix.2018, em. 13.iv.2019, C.S. Eiseman, ex Ageratina altissima, # CSE5198, CNC1990689 (1♂).

Tentatively identified material. NOVA SCOTIA: Annapolis Co., 44.93177, −65.085253, 7.vii.2021, em. summer 2021, J. Klymko, ex Eupatorium perfoliatum, #JK16250, iNat 86610348, CNC1883632 (1♀).

Hosts. Asteraceae: Ageratina altissima (L.) R.M.King & H.Rob., Conoclinium coelestinum (L.) DC., [Eupatorium perfoliatum L.], E. serotinum Michx. (Eiseman & Lonsdale 2018).

Leaf mine. (Eiseman & Lonsdale 2018: Figs. 104–105) A whitish, upper-surface blotch (beginning with a short linear portion that is soon obliterated); frass black, in scattered irregular particles and small lumps. The leaf from which the tentatively identified specimen was reared contained at least three mines, two of which had merged at the time of collection.

Puparium. Brown; formed outside the mine.

Phenology and voltinism. This species is multivoltine. Larvae have been collected in late April (OK), early July (MA, NS), early August (MA), and late August (TN), with adults emerging 20–30 days later. Larvae collected in mid- to late September (MA) have overwintered as pupae, emerging as adults the following spring (Eiseman & Lonsdale 2018).

Distribution. USA: MA, OK, TN; Canada: [NS], ON (Eiseman & Lonsdale 2018).

Comments. Although the leaf mines from which the tentatively identified female was reared were similar to those of Calycomyza flavinotum (Frick), the only Calycomyza previously reared from Eupatorium perfoliatum (Eiseman & Lonsdale 2018), it clearly is not that species, as the scutum has only limited yellow mottling and is missing the characteristic large yellow spots of that species. It is consistent with C. eupatoriphaga in having a yellowish apex on the fore femur, the orbital plate faintly brownish to the posterior ors, and the scutum faintly yellowish at the corners of the scutellum.
