On the LLP web site there there are 59 H. glacialis (Glacial Lady Beetle) reported but only a few with the extensa epithet, so I suspect they are somewhat rare. Nonetheless, I found one the other day. Googling around, I thought it was interesting that someone named Mulsant named this subspecies in 1850.
