Female Baetidae (Blue-Winged Olives) Mayfly DunFemale Baetidae (Blue-Winged Olives) Mayfly Dun View 3 PicturesThis little gal is of the usual size for Baetid mayflies, around size 20. She came with two tails, but it's kind of hard to transport size 20 mayflies without a little bit of damage.

Female Baetis tricaudatus (Blue-Winged Olive) Mayfly SpinnerFemale Baetis tricaudatus (Blue-Winged Olive) Mayfly Spinner View 5 PicturesThis female spinner was deceased when photographed, so the posture is unnatural, but it was a substantial hatch and clearly worth imitating (with wet flies to imitate the sunken ovipositing females) so I went ahead with the photos.

It was collected in association with a male spinner.
