Egg-parasitoids wasp of a water strider 3 (This is not a dragonfly.)
The final renewal day of this page is July 15, 2005.
I found several eggs of these water striders in a pond on June 31, 2005. The water strider is the insect that gets active from spring early. The Scelionid wasps are seen a lot around July.

|An egg-parasitoid wasp makes a round hole to the shell of the egg and appears. The round hole is made by cutting the shell of the egg several times thinly.|
