I get all the feeders I need into a small vial with a foam plug at the top. Get a paint brush and dabble it in the pollen mix then push the foam to one side of the top so that there is just enough space to fit the paint through inside of it. Then I just twist the brush until the pollen comes off, remove it from the vial, and shake. One thing I've noticed is that with winged flies, a lot of it gets on their wings instead of their back and they are able to clean their wings and get most of it it off.... :-/
why is it wet? Is it ground to a powder? should be ok to just put them in a small vial and shake them, but never, never, never, never, absolutely NEVER SHAKE A BABY!
The way pollen is, even if it's dry it'll stick to anything it really touches. That includes the sides of the container AND the flies crawling around (or shaken around lol) on it. It's not like how you dust crickets where they become almost while from the powder. It's on them, even if they don't turn yellow.
Yeah, why is it not dry? Easier: feed the pollen to the fly = delicious gooey center. I figure it doesn't make a difference if it's on the inside or outside.
You have to use dry, finely ground pollen. No refrigeration. I just buy Yen's Blend. Saves a lot of trouble plus you get powdered honey in the mix.
I keep a thin layer in a 16 oz. deli cup and use it to coat Blue Bottles. I drop some refrigerated flies in, swirl them around then distribute. The pollen mainly clings to the hairs on the back and gets eaten.
