Larval Tiger Beetles are in a way similar to the adults, in another way completely different.

They are just as predatory as the adults, with up to 3 pairs of eyes for excellent vision and big mandibles for a swift and brutal kill.

But larval Tiger Beetles have a completely different method for catching their food. They live in burrows which they excavate for themselves. Their large, tough head blocks the entrance and they simply wait for a hapless morsel to wander too close. At this point they lunge forward with sickening speed, grasp their victim and take it down into the darkness of their lair. A nasty hump on their back is covered in spines to keep a grip on the walls of the den should there be a struggle, and all the while those jaws do their wicked work.

Soon this demon-worm will pupate and, in time, an adult emerge. It might be spectacular, it might be about as grim as the Reaper, but it's gonna be significantly more pleasing to look at than the evil maggot it used to be.
It's a heart-warming tale in the end. The ugly, blood-thirsty duckling that became a beautiful, blood-thirsty swan, then broke a man's arm and ate it because it was blood-thirsty.
The fact that these things can't fly shows that Mother Nature has at least a little bit of mercy.
ReplyDeleteSome of them can! But not the big ones and they don't hunt on the wing. Also they don't have a taste for human eyeballs, so Mother Nature is sill merciful.
ReplyDeleteThe beautiful green ones can fly. Saw one today. It reminded me of my 9th grade biology insect collection project. I had both an adult beetle and a larva. The larva would not die in the kill jar. It took forever and was very creepy. No other specimens hesitated to keel over. Nice article!
ReplyDeleteSo cool that you get to see them! Weird that the larva survived like that. Maybe their tunnel in the ground is stinky enough that they've had to develop some kind of resistance,
ReplyDeleteGlad you enjoyed the post!
Finally found one today! Scarborough, ON.
