urbpan ask : if I use refrigeration for the flying insects. Thanks! I tried that before and it doesn't work really well. I really have no clue why they stay so still. But I have noticed that flies in particular groom like crazy. I put them in a vial like you see in some of the pictures when I catch them. They go into grooming mode as soon as I get them out. Bees do this also but not to the degree flies do. Other than that I can't explain it. Also if you see my hands looking so dry, I wash them after I hold anything . I am not a germ phobic by any means about getting dirty, I come home looking pretty rough most days. But Critters get into some nasty places so better safe than sorry. :) Warning you are likely to see dirty hands and finger nails at any time though. :o
