grub became this - Monochamus marmorator

grub became this - Monochamus marmorator
Mt. Washington, Coos County, New Hampshire, USA
Size: about 19 mm
I found a long, unusual-looking cerambycid grub under bark and this is what it became. I missed the pupa stage entirely and have so far failed to locate the larval images that belong with this adult. I'll post them when/if I find them.

Images of this individual: tag all

Moved
Moved from Longhorned Beetles.

Although far redder than those of this species posted so far, this specimen agrees with Yanega's description, especially "elytra reddish and shining."

With antennae 1.5 x body length I'd say this is a male. The image in Yanega (Plate 30) is obviously a female with antennae less than body length.

Cheers!
I remember your comment on finding this species. Glad to see you found it fast :-)

Thanks, Stephen.
I'm still a bit flumoxed by this one though.
