| scientific name Hyalophora columbia gloveri (Strecker) common name Glover's Silkmoth habitat Found in shrubby areas of the prairies and open jack pine forests in the boreal region. seasonality Adults are active from mid May to late June, with most records from the 2nd and 3rd week of June. identification In Alberta, this species is similar only to H. cecropia, from which it differs in being primarily a maroon colour, rather than black. H. cecropia also has a bright red band along the outer margin of the transverse white band, which is absent in H. columbia gloveri. Royal Alberta Museum page life history The overwintering cocoons of Glover's Silkmoth can sometimes be found attached to the stems of shrubs and small trees, usually on or near the larval host plant. Adult moths are attracted to light, but are generally not active until midnight or later. These moths are active on nights when ambient air temperature often drops below 5C?, which few other species tolerate. conservation No conservation concerns, although rarely common, this species is widespread throughout the province diet info Preferred larval hostplants in AB include Silverberry (Elaeagnus commutata), Choke Cherry (Prunus virginiana) and willow (Salix spp.). Host plant choice depends on availability and habitat; in the boreal forest, larvae are found on Choke Cherry (D. Macaulay, pers. comm.). H. columbia columbia of eastern Canada feeds only on larch (Larix laricina), but H. c. gloveri rarely if ever uses this plant in nature. However, larvae do well on larch in captivity. range Hay River, N.W.T., south to Arizona, east to southwestern Manitoba. quick link http://www.entomology.ualberta.ca/searching_species_details.php?s=267

I found one of these in my backyard, May 15,2010. I live in Ennismore, Ontario....just north of Peterborough. I have taken pictures. They are huge and beautiful. I think he''s a little out of his territory?

I found one of the huge caterpillars here in Clarkston, Michigan just Tuesday (7/20/2010). Way out of his area according to this site. When I was a child I found one of these huge moths on a wood pole under a deck roof at the public swimming pool. It was gigantic! This would have been in the mid 80''s. I''ve never seen one since until now. The caterpillar was caught by my dog. Needless to say, she mortally wounded it by destroying its head. :( But there was the rest to identify it with. It looks just like those you have here on the site. What kind of trees do they eat. The only ones near by was a Mulberry and Box Elder.

We found TWO of these huge caterpillars about August 18, 2010, north of Spirit River, Alberta. Both are now cocoons and I wonder how we can "raise" them and hopefully produce MORE of them.
