Figure10-1Larva that hatched and the egg of the water strider of a host
The water strider of the host looks like the species that inhabits in the running water area. This egg was adhering on the surface of the tree that soaked it in water. I collected those eggs on February 6, 2004.  (Figure 9-1 has been cut down in 1/2.)
