Just saw my first on some yarrow I was harvesting. Hopefully they wont be like the deer this year…those beautiful boogers have eaten almost entire garden!
The Winsom Fly (Istocheta aldrichi) may be emerging from its pupal stage too early in the southern states to be a meaningful predator of the Japanese beetle, but in Connecticut and Canada, cooler spring weather causes better timing between predator and its beetle host. You could also look into Spring Tiphia (Tiphia vernalis) which ranges as least as far south as Tennessee and might be a better candidate for southern gardeners. Summer Tiphia (Tiphia popilliavora) may also be worth looking into, but I don't have any data. You mentioned parasitic nematodes and the Heterorhabditis species is reportedly effective.
It has been a prolific year for these pests in our area. While weeding by hand in the lawn I located a 'clutch' of 79 pupae in a 1 square foot patch, and many more smaller clusters intermittently throughout the lawn. I'm eager to try the traps. Thanks for the tutorial!
