Something's happening here

What it is ain't exactly clear. There's a bug with a snout over there, telling spider it's got to beware . . . okay, enough of that. I keep getting tricked by insects that are somehow impervious to spider webs. At first I thought that this assassin bug had been caught and would be devoured. But when I came back a few minutes later, it was gone. So I do not know who was after whom.
