|scientific name Spilosoma pteridis |
common name Brown Tiger
Found in moist meadows of the boreal forest.
The Brown Tiger looks more like a Phragmatobia than a Spilosoma in size and markings; however, there is no red colouration characteristic of Phragmatobia species.
The extreme rarity of this species may indicate that it is a habitat specialist, possibly associated with peatlands and fens.
Several specimens in the Northern Forestry Centre collection were collected from and reared on fireweed.
This species has a fairly limited distribution, occurring from southwestern Manitoba west to southern B.C., south to northern California. There is only one record for Manitoba, and there are currently no known Saskatchewan records.
