japanese beetle - Istocheta aldrichi
Merrimack, Hillsborough County, New Hampshire, USA

Tell me- most of the j. beetles I see have those white mites on them- what parasites are they?

Moved
Moved from Japanese Beetle.
We already have many Japanese beetles, but not so many I. aldrichi. It is better here.

The white "mites" on your Japanese Beetles ....
These are the eggs of the imported and deliberately introduced parasitoid fly, Istocheta aldrichi, which is the natural enemy of the Japanese Beetle in Japan. See also http://bugguide.net/node/view/5387 .
