If you find an insect with two tails in a stream, chances are
it is a young stonefly like me...
Scientists call me Zelandobius and I am one of the most common
types of stonefly. I sometimes crawl out of the water to go exploring in the
moss on the tops of stones. Most stream insects can't run around above the water
like I can.
Some of my stonefly relatives are much bigger than me and they
can be quite scary looking. The biggest stoneflies live in streams with big
stones, but since I'm smaller I'm quite happy living in gravely or sandy
streams. The biggest stoneflies can only live in very cold water, but I can live
in streams that are not so cold.
