Case of the Week 302
Several small dark-colored irregular "soot-like" objects (~1/4 inch long x 1/8 inch wide) were found floating on the surface of murky water in a neglected bird bath in late Spring. One such cluster was scooped out mostly intact and mounted on a slide for further examination. It is shown below. Identification?

I'm not a mycologist... but these would appear to be fungal spores of some sort.
I would guess its a mosquito egg packet. Culex species?
Mosquito (culex) egg rafts
I go with mosquito egg bundles. bw in vt
Mosquito egg rafts. I used to raise mosquitos and fed the females on my arms. They required a blood meal to produce eggs.
I agree. It looks like mosquito egg rafts!
Culex mosquito egg rafts
After in-depth research on google images ;) , Culex mosquito egg rafts.

Culex egg raft. Anopheles eggs would have lateral floats, Aedes doesn't lay eggs onto the water and Mansonia's eggs are laid just under the water surface (and have a spiny ending).
That's an entire collection of answers. I would go with Tomas's answer.

Agree with Culex eggs which are stuck together in rafts. However, this characteristic is not specific to Culex only, as Culiseta's eggs can be also arranged in rafts.

I think this is a culicine mosquito egg raft.
probably of the genus Aedes.
I think our hostess of the mostess weirdness is on vacation this week possibly plotting a really tough case.
