Two Phryganeidae caddis larvae fighting over a case
Caddisfly larvae of this family can easily leave and re-enters their cases. I caught two of them playing musical chairs or something with this one... funny!

I had excellent luck sampling burrowing mayfly nymphs here in the headwaters of a trouty small stream. From the Marengo River in Wisconsin.

I had to really search for a while to find a sliver of opening water at this sampling site far in the headwaters of a mighty warmwater river. From the Far Upper West Fork of the Chippewa River in Wisconsin.

Phryganeidae Caddisfly LarvaPhryganeidae  Caddisfly Larva View 5 PicturesThis "specimen" is actually two caddis larvae fighting each other over a case. The case is a hollow tube; one larva would go in the back end, presumably bite the other, and chase it out. The invader crawled forward into the case while the other one fled, and then it went around to the back and bit the first one. They did this several times, and I recorded it on video.

Baetisca laurentina (Armored Mayfly) Mayfly NymphBaetisca laurentina (Armored Mayfly) Mayfly Nymph View 3 PicturesI took a few group picture of a bunch of Baetisca laurentina nymphs to show the degree of individual variation in size, color, and shape that can occur within the same species in the same pool of the same river. This variation is one important reason why trout are forgiving of some small degree of variation in our imitations--the naturals themselves vary, too.
