Insect ID in pots of cut flowers
I work in a grocery store chain and occasionally fill in for the regular floral specialist. Most of our flowers are cut and placed on the floor in black, plastic pots. Sometimes when I come in, the water in these pots has not been changed in at least a week, and there are tiny, light brown insects approx. 1-2mm long that fly up out of the pots when I lift the flowers. I can't provide a photo b/c they're too small and probably too quick for my camera. This happens in all the flower pots that are neglected, no matter the type of flower. The water is usually the same light brown shade and sometimes there is a slushy ecru-colored deposit in the bottom of the pot. I know how to get rid of the bugs (clean the pots and refresh the water), but I am just curious to know what they are. The floral specialist does not know.
