The lamest way to die as an insect must be getting stuck in a spiders web that doesn't house any spiders, amirite?

Phantom spiderweb

I just kinda sitting here waiting to die, too.

The best is probably getting swatted by a human. To a fly you're a nigh-immortal god who will live for thousands of their generations, you're huge and your waste can feed them, you comprehend concepts so far beyond them. We are Lovecraftian gods to bugs. Getting swatted by a human would be like a human getting personally targeted and crushed by Cthulhu.

The equivalent in humans would be war booby traps with the enemy fleeing forever.
