Swimming insect? in Pak Chong, Thailand
Location: Pak Chong, Thailand

Hi. This thing is swimming in our pond in Pak Chong, Thailand, a mountain/jungle region in North Eastern Thailand. It’s several centimeters long, and seems to have 6 legs that it uses to swim. Hangs out both under water and on the surface. Not sure if it’s some type of dragonfly nymph? Any ideas? Thanks.
This is the larva of a Diving Beetle, most probably a Predaceous Diving Beetle. They are sometimes called Water Tigers.
Thank you for the very quick reply. So the ones in our pond look much younger and less developed than some of the photos I’m seeing. I guess I can expect changes to be upcoming.
Will this larva begin to eat the small fish in the pond (1 cm)? So far these things hang out near the light at night and have made no move to attack any fish as far as I have seen.
Hi again Andy,
Water Tigers will eat small fish.
