Last night when I was chopping a hole in the ice to get my water, I saw something that I’d never seen nor heard of before (or at least had not taken note of). When my ice chisel went through and the water came bubbling up, there was a positively massive beetle in it that was very much alive! Isaac proposed that it may have been attracted to the light from my headlamp, which seemed a reasonable assumption, and a little bit of internet sleuthing has confirmed his suspicion.
Here is what I have learned:
The beetle was of the species Lethocerus americanus of the family Belostomatidae. Its common names include ‘Giant Water Bug,’ ‘Electric Light Bug,’ and ‘Toe-biter.’
They eat worms, tadpoles, small fish, other insects, salamanders, and small frogs which they kill with an injection of an enzyme that poisons them and begins digesting them at the same time, which is why bites can be pretty painful to us human-folk. (Imagine if we hadn’t told Seth it was in his water-bottle.)
Giant Water Bugs can fly, and do so predominantly at night, when they are believed to navigate by celestial bodies, or, in modern times, any other source of light, giving them the name ‘Electric Light Bug.’
I did take a picture of ours, but I have forgotten my camera at my shack, so I will post the picture at a later date (though I have included a public domain image for now).
