Bingo.

We found them.  Referring back to the previous post, as our readers know we've been looking for spotted wing drosophila pupae under fruit in raspberries, and now on the second read have confirmed that they are indeed pupating within a centimeter of the fallen fruit.  In the meantime, the pupae collected on the first read have eclosed and the adults are SWD.

Pictures below.  Really nice work on the part of Staff Research Associate Monise Sheehan on figuring this out.

Looking to do a bigger run of the same late this summer and then get a nice paper written about it.

Soil from underneath raspberry just pulled back a hair, brown indistinguishable mass in the middle is the pupa.
