Wasps in the Eucharitidae family are parasitoids. Parasitoids live in their hosts consuming them until they are ready to become independent at which time they emerge from the host (the host dies in this process). Think the alien in the movie, Alien.
The wasps lay eggs on leaves and the larvae hitch rides on ants back to the colony and then infect an ant larva. When they emerge from the host they are groomed and fed by the ants who apparently confuse them for other ants.
The wasps mate as soon as they emerge from the ant colony and the females lay all their eggs in a single day.
Each species of wasp parasitizes a single genus of ant.
Looooooove these! Specialized parasitoids of ants! :D
Soil liquefaction is a rather unsettling process in which apparently solid ground begins moving in a fluid-like way after agitation. It occurs in loose sediments when the spaces between individual particles become nearly saturated with water. This can happen, for example, after heavy rains or in a place with inadequate drainage. Such cases are typically very localized, though, and require some significant agitation of the surface, like pressing with heavy machinery or jumping in a single spot. Soil liquefaction becomes a greater danger, however, in an earthquake. Even in a dry area, the earth’s shaking can force groundwater up into the surface sediment and vibrate the soil sufficiently to liquify it, causing whole buildings to sink or tip and wreaking havoc on manmade infrastructure.

Polish photographer Ireneusz Irass Waledzik uses macro photography to beautifully reveal the awesomely complex and colorful anatomy of insects, in this case their amazing compound eyes.
"I love macro photography, I spend a lot of time at it. The different shapes of insects’ eyes fascinates me. These bugs are bling and it must be so important to them to show bright and colourful markings; they might be small but they have a big impact. I want to show the world the amazing insects unnoticed to the naked eye."
