|scientific name Meris patula |
Adults fly from late July (?) to early August.
A non-descript mid-size grey geometrid. Wing ground colour white-grey with an even dusting of grey-brown scales. AM and PM lines diffuse and jagged. Hindwing slightly paler.
Nothing is known of this specie's immature stages. It is known only from the the type series of six specimens, one of which was collected 9 miles north of Coaldale, AB by D.F. Hardwick on August 4, 1961 (Rindge 1981).
Known globally from only two sites, one of which is in southern AB.
The larval hosts are unknown. The larvae of Meris alticolata feed on Penstemon virgatus in Arizona (Rindge 1981), so it is possible that M. patula feeds on Penstemon or other Scrophulariaceae.
Known from southern Alberta and south central Montana (Rindge 1981).
