The Tiny, Tiny Water Boatmen

on
30 March 2012

The Water Boatman (Notonectidae) is also known as a backswimmer, precisely because they swim upside down on their backs. These tiny swimmers are not often noticed, as they swim underwater, unlike water striders and fishing spiders which skim across the water surface. The water boatman has a pair of powerful hind legs with long hairs modified for swimming – much like how humans use their legs in the breast stroke.

  17. It has this habit of flattening it’s body on the underside of a leaf. Their way of taking cover perhaps?

  20. Comb-footed Spider (Theridiidae) with Pseudoscorpion - DSC_5103
  21. On closer inspection, the prey was a Pseudoscorpion! These guys are usually about 2-3mm long, so that gives us an idea on the size of the spider.

  29. Red Tent Spider (Cyrtophora unicolor) often found in a massive, complicated web but this time it was out. Once we approached it, the big fella tried to play dead

  31. Spinning on it’s web

  32. Red Tent Spider (Cyrtophora unicolor) - DSC_5177
