The cool weather this spring has caused the emergence of adults from the soil to slow down. Heavy spring rains early on followed by relatively drier weather in late June may have trapped adult Japanese beetles under a crusty layer of hardened soil. This could explain why there has been a decrease in the number of adults seen this long do japanese beetles stay around_1

Tachinid flies are parasitoids of Japanese beetle adults, and are therefore one of the natural enemies of this species. Tachinid flies are true flies (Diptera) in the family Tachinidae, of which there are over 1,500 known species. They can vary in size (3-14 mm) and color (black, grey, and orange).

Lawn grubs are the larvae of a number of different kinds of beetles, including Japanese beetles, European chafers, and May/June beetles. They hatch from eggs laid in the soil, and spend the majority of their lives underground, feeding on the roots of grasses.

Lawn grubs can cause extensive damage to lawns, particularly if they are present in large numbers. They are most active in late summer and early fall, when they can be seen crawling around on the surface of the lawn in search of a place to pupate.

If you suspect that you have a lawn grub problem, the best time to treat them is in late summer or early fall, before they have a chance to do too much damage. There are a number of different products available for controlling lawn grubs, including insecticides and nematodes. Be sure to follow the directions on the product label carefully.

It is thought that the beetles are attracted to the release of plant oils when the plants are being chewed, rather than to the presence of other beetles.
