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.

Figure16-2　I took this photograph on July 12, 2005. Soon wasps appear from these eggs.

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.
