Hey! Could I get some help IDing these little fellas? My mom found them in a lake in Texas, they’re about 5-6cm long. She’s a flyfisherman so she’s always really excited about learning about aquatic larvae in areas she fishes! I’ve been digging through lists and guides of aquatic invertebrates/larvae and haven’t found anything quite like them, care to help me out?
These fat babies are water scavenger beetles. I’ve never been blessed with seeing them in person, but I have seen the adults. They can be small, but they can also get very large! Here are a couple from Austin:
These were both seen in March 2018. Sorry it took me SO LONG to answer you life is stressful!
