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?

  1. I'm not a mycologist... but these would appear to be fungal spores of some sort.

  4. Mosquito egg rafts. I used to raise mosquitos and fed the females on my arms. They required a blood meal to produce eggs.

  8. 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).

  9. That's an entire collection of answers. I would go with Tomas's answer.

  10. 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.

  11. I think this is a culicine mosquito egg raft.
    probably of the genus Aedes.
