clamworm hatches happen year round BUT are more prevalent around may june. These fish when caught will usually have dark wormlike creatures in their gullets

Or little black stringy things as Ive heard them called.... which would be a give away that they've been feeding over some very rich muddy waters.. like ummmmm where these hatches occur
The shallow water and radiant heat Im sure has something to do with it as well. They leave the ponds and round the bend to warmer water, grub up then boogie back and go nighty nite.
Kids do have fun with them though dont they

Too bad theyre too little to carry tags, it would be a pretty cool study
