Thanks for sharing. I have always leaned more toward gray colors for calli's. Now I have to burn an entire box of flies! Great pics!!
The coloration of a nymph can be due to it's environment, species, and stage of development. I think you have to know how to match nymphs for a given area.Certainly the adults can have a distinct gray cast to the bodies (and tans, and gray-tans). I always feel a little like the surrounding environment plays a role too. While I can't say the nymphs are exactly transparent, I have to think that one swimming through a grass mat is going to have a more olive look than one swimming over a mud bottom (or seen backlight against a blue sky).
Mark, the dark wing buds/pads? There seems to be considerable variation. Any insight there? (I've always been told a dark "wing case" means 'about to hatch,' but always thought of it as more the whole thorax top, not just pads.)

The wingpads in these pictures are about half-way to emergence (the 2nd and 3rd pictures) and very close to emergence in the ones that are black. Those that are black will probably emerge in minutes to hours.
This is great info! I'm going to add black goose biots to rep the wing pads when I get back to cali's. Thank you!The coloration of a nymph can be due to it's environment, species, and stage of development. I think you have to know how to match nymphs for a given area.
