This was a difficult choice These are my reasons for choosing Caloptilia burgessiella over the four other Caloptilia species with only two yellow spots on each forewing.
Caloptilia bimaculatella: first spot too large
Caloptilia canadensisella: has small yellow tornal spot and no dark dots in first costal spot.
Caloptilia cornusella: too purple. costal spots too far apart, no semicircular curve and no dark dots in first costal spot.
Caloptilia umbratella: too purple. some yellowish-brown spots are often evident after the 2nd costal spot. This was the closest match to Caloptilia burgessiella
Caloptilia burgessiella: Fore and middle tibia dull black. Tarsi and hind legs whiteish. Face white to antenna bases. Top of head brown. Palpi white with short black tip. Thorax brown. Antennae vertex brown. Forewing umber brown with purple iridescence. First spot on wing semi-circular enclosing 2 tiny dark dots along costal edge. Second mark quadrate, 2 times as long as wide. No subterminal bars on costa. Fringe fuscous with faint lines in apex. Wingspan: 11 - 14 mm (Forbes, 1923)

Adult Markings: The face, palpi, tuft, and antennae are white, except for the extreme tips of the antennae which are dark brown. The thorax and basal two-thirds of the forewing are shining white, while the apical third is suffused with golden. A rather broad golden basal streak begins at the base on the costa and extends parallel to the fold to the middle of the wing or beyond. In the apical golden portion of the wing, there are three costal white streaks that are nearly perpendicular to the margin. All three have dark margins on the anterior side, but the margin is best developed in the anteriormost streak. A dorsal white streak with a dark anterior margin occurs opposite the first costal streak. A second indistinct dorsal streak that often lacks the black margin occurs opposite the second costal streak. There is a conspicuous black apical spot, and the cilia are whitish, but tipped with fuscous around the apex. The marginal line in the cilia is dark brown. The hindwing and cilia are pale grayish ocherous, and the legs are whitish ocherous.

Phyllonorycter quercialbella closely resembles P. argentifimbriella but it has only three costal streaks, compared with four in P. argentifimbriella.

Marasmia trapezalis (Trapeze Moth). Photographed at Wilson Tract, Norfolk County, Ontario on 19 July 2020. A new moth for Ontario, and perhaps Canada? Thought at first to be Trapeze Moth (Cnaphalocrocis trapezalis), but size and appearance are at odds with it being this species. It was sitting on the very last egg carton at the bottom of one of the traps! A total surprise and not a moth I ever expected to see in Ontario. I had seen Trapeze Moth (Cnaphalocrocis trapezalis) just once before in GA a few years ago. This species is very similar to Cnaphalocrocis cochrusalis (Marasmia Moth) and I based the initial id on the fact that the lines on the FW and HW do not match up, ie. they are "stepped" and that the AM and PM lines are relatively close together at the inner margin of the FW. However, it should be noted that these markings may not always be solid id features. Observed with Michael King, Mary Gartshore and Peter Carson.

FWL = 7 mm

This photo was identified by David W Droppers as Caloreas apocynoglossa https://www.butterfliesandmoths.org/sighting_details/1254539
which seems pretty far out of range (California & Montana according to BugGuide and Moth Photographers Group). In Ferris et al A Checklist of the Moths of Alaska the only Caloreas is called "Caloreas new species" with a note which reads: "The CNC has paratypes of a species that is being described by J. B. Heppner (monograph in preparation with projected publication in 2013)." I have not been able to find any work by Heppner on this.

I have also submitted this to BugGuide and will update this sighting if and when I get more information.
