Not really raining, Montlake Fill

This morning we had the kind of precipitation that Seattlites often call "not really raining." The expression applies to two distinct types of weather. One is a slow drizzle. The other is a light mist with drops so tiny that they don't fall to the ground but waft with the air currents and pool on the surface of your skin. It's not really raining, but more like a cloud coming to ground. It's not fog - you can see things, sort of. Here's the 520 bridge.
In fact, the not-really rain illuminates things that we overlook on clear days, such as the tiny webs of spiders, still active in February.

Dome spiders mating, Discovery Park

At this time in summer, spiders and their webs get larger and more conspicuous. In Discovery Park, the most often seen types are orb webs, and dome webs.

Here's a dome web.


And here are some more. In most of the webs, a single spider sits upside-down in the middle.


But some had two spiders, who were busy making more spiders. Here's how spider making works: the male (on the right in this picture) carries sperm on his palps - a pair of appendages in front of his fangs. (The male in this pair had red palps, as if he was holding a pair of boxing gloves.) The palps fit into the epigyne, a plate under the female's abdomen.

Both palps and epigyne are shaped so that only males and females of the same species can link up.

Here you can see the male's palps. I thought they looked like tiny boxing gloves. A couple of times, they unhooked, and quickly backed off each other. Then the male would move toward the female, plucking at the web as he came forward, and they'd clasp again.

This web had three. The male is at the bottom. A female is just above him and a second female is in the upper strands. How did that happen?

Zebra jumping spider and breakfast


As seen on the pineapple sage in my driveway.
I love how jumping spiders look. With the furriness and the big carnivore eyes they look almost cute -- but not quite.
