| scientific name Hemaris thysbe (F.) common name Hummingbird Clearwing habitat Open woodlands, edges and clearings and adjacent meadows. seasonality Adults are on the wing late May - July. identification A fairly large (4.5-6.2 cm. wingspan) day-flying moth with narrow, pointed translucent wings. The wings have dark olive brown (forewing) or red brown (hindwing) bases, a wide dark outer margin, and the veins are lined with dark scales. The heavy body is covered in dark olive-brown hairs, except for a wide dark band on the abdomen. In Alberta, it can be mistaken only for the Snowberry Clearwing, which is smaller, has narrow dark outer margins on the wings, and large yellow patches on the sides of the lower abdomen. The very similar Slender Clearwing (H. gracilis) has been reported from eastern Saskatchewan and may eventually turn up in eastern Alberta. H. thysbe can always be told from other species of Hemaris by the row of dark scales bisecting the forewing discal cell (absent in other Hemaris species). Royal Alberta Museum page life history The Hummingbird Clearwing is most often encountered during the day while nectaring at flowers. Unlike the Snowberry Clearwing, it is frequents open woodlands throughout much of the Boreal Forest region. It rarely alights, and the wingbeat is so rapid the wings are a blur, and thus it greatly resembles it's namesake, the hummingbird. conservation No concerns. diet info No Alberta data. Elsewhere reported to use various shrubs, including Viburnum, Honeysuckle (Lonicera), Cherry (Prunus), Hawthorn (Craetagus) and snowberry (Symphoricarpos). range Occurs throughout most of the wooded parts of eastern North America, west accross the boreal forest region to B.C. and Washington. In Alberta it is found throughput the boreal forest, the northern part of the aspen parklands and in the foothills and lower elevations in the mountains. quick link http://www.entomology.ualberta.ca/searching_species_details.php?s=545
