This is one of two water striders that I caught on the little stream that runs alongside of our road. They are normally almost impossible to catch, but I spotted a pair that was mating. They were moving pretty slowly, and I was able to corner them up against some rocks and nudge them into my collecting jar. They unfortunately stopped mating by the time I got them home, so I couldn’t get a picture of them both at once.
Water boatmen, like this one, are all over the place. They can fly, so they end up in bodies of water ranging from full-blown lakes, to puddles and birdbaths. This particular one was at the mouth of Cole’s Creek, just down the road from our house.
The back part of our property drains into Cole’s Creek, which empties into Portage Lake about a mile to the west of us. It’s a pretty substantial stream, and one of the better places for catching smelt[1]. S_ has been going down there from time to time to check if the smelt run has started, so last weekend she suggested that we all go there to poke around in a stream bigger than the one beside the house and see what we could find. We probably didn’t find anything that isn’t in our little micro-creek[2], but we did find some photograph-worthy specimens. Like these guys:
An accidental capture
So, while we were capturing the Gammarus for last week’s entry, we scooped up some water from the stream into a jar to put them in. In the process, since the stream was so shallow, we got some debris off of the bottom into the jar, too. Then, when we got it back to the house and started looking at what we had, S_ noticed that one of the bits of debris was oddly symmetrical and had a hole in one end[1]. So, we put it into the petri dish along with the amphipods, and waited to see if anything came out. Something did:
Not really a freshwater shrimp
Last Sunday, it was pretty warm, and S_ suggested that it would be a good day to take Sam down to the stream[1] to turn over some rocks to see what was underneath[2]. So, I grabbed this rock that was in the middle of the stream, turned it over, and found about 20 of these clinging to the bottom:
