Tetragnatha extensa - male

Tetragnatha extensa - Male
Deadman Lake Campground, eastern Alaska, near Alaska Hwy, Alaska, USA
September 1, 2009
Size: 6.5 mm
Here's the palp--not a great photo, but it shows the curved hook at the tip of the conductor (amongst the hairs at the tip of the palp in the lower right of the photos) which is diagnostic for the species, as seen in Dondale's book.

Macro?
Hi Susan,

Looks pretty good to me -- was that shot with a macro lens?

shot thru dissecting scope
This photo was taken thru the trinocular port of my dissecting scope with my new Nikon camera on an adapter and using an led ring flash attatched to the objective lens. I'm still learning how to do this. Sometimes my photos come out good, sometimes not so good. I think part of my problem is I need better lighting than provided by this ring flash. We were on an extended camping trip and altho we had a generator along, I didn't bring lights that required firing it up. The photos of the whole spider were taken with a macro lens and the regular flash.

Ah, that explains why we can see so much. I find the Tetragnatha and their very tiny conductors to be devilish to deal with -- at least under my microscope.
