Field Notes

Description:

I found several of these massive grubs in the watery hollow under an uprooted tree. They were about 1" thick and probably 4" long (25mm thick, 100mm long). The tape measure pictured is in inches. I've added an image of the uprooted tree and the hollow space full of water where I found them.

I added a picture of the uprooted tree. I'm not sure how recently it was knocked down, but I think it was fairly recently. Maybe they were never intended to be in water.

It may be they weren't meant to live in water. The water was in the hollow space under the roots of an uprooted tree, so maybe it would have been just dirt before the tree was knocked over. However, the one I pulled out was alive but slow and sluggish.

Scarabaeidae, Dynastinae. Should be a Rhino Beetle Larva, but I cannot tell you which genus/species. And I do not know how they came into the water, maybe incidentally or fallen from a fruit of the tree? http://bugguide.net/node/view/53842/bgimage http://www.biolib.cz/IMG/GAL/BIG/167533.jpg http://www.allmystery.de/dateien/mt47424,1229337173,Hercules_beetle_grubs.jpg http://bugguide.net/node/view/621553/bgimage http://bugguide.net/node/view/2876/bgpage

Uups! I did not notice that you found them in the water! Sorry! Then we have to look further...

Looks like a beetle larva from the family Cerambycidae, Longhorn Beetle. http://bugguide.net/node/view/162214/bgimage?from=0
