Osmoderma sp. larva - Osmoderma
Dr Bruce D. Gill of the
www.inspection.gc.ca thinks that, if he is not mistaken, this larva is very likely Osmoderma eremicola or Osmoderma scabra, they are common in the Toronto area.
The fecal pellets of these Trichiine larvae are shaped like miniature chiclets (a type of chewing gum), clearly visible in the photo.
Now we need a kind soul to add the Subfamily Trichiinae to the Taxonomy page
here and remove this Genus, and perhaps others from the Cetoniinae into the Trichiinae, please.
I've learned quite a bit while trying to get an ID for this interesting larva. Apparently both Osmosderma eremicola and
Osmoderma eremita, an Old World species, smell of Russian leather, which has been discussed
here.
What is the smell of Osmoderma scabra?
