Three Haploa Moths

Haploa confusa: The antemedial white patch is two-lobed at the distal end in Haploa confusa, as opposed to elliptical in Haploa lecontei.

Haploa reversa: A distinctive white triangular patch extending from the thorax (the segment between the head and abdomen) to over half the length of the wing. There are three similarly sized, distinctive white patches on the leading edges of the front wings. (https://www.ontario.ca/page/reversed-haploa-moth)

According to https://www.canada.ca/en/environment-climate-change/services/species-risk-public-registry/cosewic-assessments-status-reports/reversed-haploa-moth-2019.html :

" A colour form of Confused Haploa Moth (form triangularis), with an extended basal white patch that lacks the dark sub-basal brown bar that is usually present in that species, is very similar to Reversed Haploa Moth and often misidentified as such. This [Confused Haploa Moth (form triangularis)] can be distinguished from Reversed Haploa Moth by the more irregular shape of the basal white patch, smaller costal white patches, broader dark border of the inner (anal) wing margin, and overall smaller size (forewing length usually fewer than 20mm).
