Extreme Freeloading Tiny Tricky Parasitic Wasps
It is one thing to inject your own eggs into another insect's eggs so your young and eat the young of another creature, it is yet another level to conniving (though certainly logical) to then also hitch a ride on the parent of the egg you are parasitizing! This is exactly what the tiny, tiny wasp Hydrophylita emporos in parasitizing damselfly eggs. When the damselfly lays the eggs underwater, the wasps crawl down the abdomen and egg their eggs within the egg the damselfly just put down....
Way to go Andrew Polaszek at London's Natural History Museum, nice find!
Here is a video of the critter at work
