Tadpole Homework

by Jack Phillips

Last week some young people were looking for a different style of remote learning. So I met them at a quiet pond in the southern Loess Hills and there we drug our dip nets through the bottom litter and gunk to collect our treasures of larva and naiads, mussels and minnows, little sunfish.

Tadpoles are always a favorite and in October in these parts they could only be one species. And what species is that? The kids were not particularly pleased when I assigned some homework, but I wanted them to figure it out for themselves.

I suggested that they use our friend Jeff LeClere’s Amphibians and Reptiles of Iowa (http://www.herpnet.net/Iowa-Herpetology/amphibians/frogs-and-toads-2/) to identify our tadpoles. Can you? Even if you think you can identify them by appearance, read Jeff’s species accounts to get schooled on the life cycles of Loess Hills amphibians and why there is only one possible answer.

Here’s what our little tadpoles will look like next summer!
