Depending on size of sample from any trap, we use either 14cm glass petri dishes or 9cm plastic dishes, and when sorting we follow the strips of masking tape on bottoms of dishes to avoid missing anything.

And for those budget-minded recyclers, the more quadrate tofu containers (roughly 4” x 5” X1” deep) make fantastic sorting trays. They are white, flat-bottomed, fit under the scope nicely with room to maneuver featherweight forceps, and are molded from HDPE so ethyl acetate and alcohol are not an issue. I use them for sorting pitfall and V-FIT samples and save them every time buy tofu to make Thai curries.
We have used the Rose Entomology sorting trays for years, they are great. Now sold by Bioquip apparently, as sadly John Rose has passed away:
Big petri dishes probably still work better for really big stuff, but for little things (which are the best anyway), these trays are superb. The ridges are just right for sorting under a dissecting scope.

Since we are on the topic of glassware. Anyone have some favorite containers for sorting Malaise trap samples? We have been using deep large plastic Petri dishes for ages but they have gotten old and are cracking. We generally sort into muli-cell culture plates. Any tips and tricks appreciated.
