The emerald cockroach wasp can mind-control cockroaches by injecting venom into the roach's "brain"/nervous system. The roach then becomes docile and allows the wasp to lead it to a tomb, lay eggs in it, and seal the tomb until the wasp larva hatch and begin to eat the roach alive!

forgot a period. anyway - it's not much but it's a really great resource for me to connect and learn from other locals, especially for cryptic species in my area
