Blue Winged Olives, Baetis tricaudatus

Todays piece will focus on patterns that will work on spring creeks now..


Baetis nymphs are active swimmers. They hatch with water temperature as low as 46. These bugs are multi-brooded  (Three broods per year.) They emerge by crawling. You will see them in the morning and afternoon with the main activity from noon until evening.

Todays discussion will be on nymphs, tomorrow emergers.



Nymphs are streamlined vigorous swimmers. They are light to medium olive-brown, size 18, with a brown head with pale patches on each side of mid-line. Their gills are slender with small gill plates. They have 3 tails; the center is shorter (half the size of the outer 2.) Tails are banded at mid length and the tips.

Baetis nymphs can be imitated with a size 18 hook, standard length. They are tied with an underbody of fine lead. Use olive thread, natural wood duck for the tail and legs, with a body dubbed with olive angora rabbit. The covert is made of iridescent green or blue feather from a pheasant or mallard, or peacock.


A pheasant tail also makes a good imitation.
