Wasp - Sceliphron caementarium

Wasp - Sceliphron caementarium
Western shore of Whidbey Island to the north of Mutiny Bay atop a bluff, Island County, Washington, USA
August 18, 2006
Size: 20-30 mm
Unknown wasp. It is one what I am told is some type of laurel. I am unsure of the species and it is not either of my books (Pojar & Mackinnon, and Kozloff's Plants And Animals Of The Pacific Northwest) so I suspect it is an introduced species. But I will research that later. The plant does seem to attract a disproportionate number of wasps.

Moved from Sceliphron.

This is a Sphecid wasp of the genus Sceliphron. They built mud-nests and hunt spiders. They often get introduced into other places, but I'm not sure if this one is native to your place or not.

Thanks Martin. I will post m
Thanks Martin. I will post more shots of this specimen or one of a couple of others I have shots of (I will have to go back to the RAW files and review to see if I have others of the same specimen).

S. caementarium.
This is indeed the common black and yellow mud dauber, Sceliphron caementarium. Individual variation can be extreme. Down here, these wasps are usually much more heavily marked with yellow than in northern specimens such as yours. There are only two species in the U.S., and the other is restricted to Texas as far as I know. Very nice shot, btw:-)

Thanks Eric. :o) With that huge wasp waist they can be spooky when they sneak up on you (makes me feel like prey for a moment).

You can see the full frame if you are so inclined. I think the full shadow adds to the image (but does not help with an ID). :o)
