Well, it woulda been more appropriate in April 25, perhaps — though the species is not a malaria-carrying mosquito.
Still, you gotta love it, Wikimedia’s Picture of the Day for April 30, 2008:
Culex spp., larva, near the surface of a body of water.
This would make a great background for a PowerPoint presentation with just a bit of work, I think. The browns are about the same intensity as the blues and greens. Nice background for a presentation on mosquitoes — outstanding background for slide of a chart on mosquito populations or somesuch.
Warm up for biology class: Invert the photo, ask kids to explain what it is.
