Tiny Black Spiders - Entelecara acuminata - Male Female
Puyallup, Pierce County, Washington, USA
May 25, 2008
Size: around 2 mm
Found these tiny dwarf spiders mating on my window sill. The male had his palp stuck in the female. I would say dwarf spiders. These match the drawings of Erigone sp. in A Golden Guide to Spiders exactly.

From Rod Crawford...
Definitely not Erigone - they have teeth around the edge of the
carapace. Microscopic examination needed for positive ID. One
possibility would be Pelecopsis sculpta, but that's not something I'd
really expect on a windowsill (they're moss spiders).

Did You

Nope
just took advantage of the show. I took about 200 shots of them. :)
