scientific name    Alypia langtoni    

common name     Langton's or Six-spotted Forester

habitat
Widespread in Alberta, found throughout the wooded areas except in the grasslands region.

identification
A medium-size (approx. 3 cm wingspan) jet-black moth with 2 large pale yellow or cream spots on each forewing and one (female) or two (males) large cream or white spots on the hindwings. The tegulae (scale patch on "shoulders") are pale yellow, and the legs have orange tufts. Other Alberta Foresters have prominent black linings along the veins across the spots, giving them a striped appearance. These are absent or very faint in lantana. A smaller pyralid moth (Anania funebris) is superficially very similar, down to the yellow tegulae, but is much smaller (1.8-2.2 cm wingspan) and less robust.

life history
There is a single brood in Alberta, with adults from early May through early July. Adults are diurnal and visit flowers for nectar. The larvae feed on fireweed (Epilobium sp.) The colorful caterpillars (orange speckled with black and with sparse long setae) are illustrated in color on several sites on the web.

range
Newfoundland to AK, south to ME and WI in the east, south in the west to at least CO and CA.

notes
This pretty little moth tends to be rather rare, and I have yet to see a live one.

This is the second year that I have had one on the screen of our sliding glass door. It hangs out for a day and I finally researched what type of moth he is. He is very pretty. I took pics if you would like one I can e'mail it to you.

I'm in Northern Indiana on a 100 acre farm that is pretty overgrown and not farmed much over the past 30 years.

My daughter is near Ashtabula, OH, on the south shore of Lake Erie and just sent me a picture of one at rest on a cobblestone beach (05/25/2013). Glad I found this website to send back to her.

A eight spotted Forrester ( I think it would be a male)was on my sidewalk at miday on May 26, 2014. I live in Arden, NC (near Asheville) at 2600 ft of elevation. I have a photo.

I found one of these in the Death Valley area in Kananaskis Country, west of Millarville, Alberta, Canada on Father's Day. I have a photo of it as well, available here: https://www.flickr.com/photos/ubermoogle/18442808404/
