Name That Bug


Recommended Posts

Jfisherman here, Paulf, is that a blue winged olive in picture #1 because that looks (at least from a distance) an awful lot like what was hatching at Hawrelak on Sunday (the 13th). To get a closer look I captured one and it had a body awfully close to that in the picture with splotchy brown wings.

Is Paul being Tricksy?

Looks like two different bugs to me.

Both mayflies of course.


The first one has sightly opaque wings and a dun colored body.

A Pale Morning Dun immitation would work regardless of species.

Say an Adams or (gulp) CFF in the right size.


The second has transparent wings and a light olive body.

A blue winged olive pattern in a larger size with light olive body might work.

An olive biot body parachute (RS Quad) would be a good choice.


So regardless of the actual species, one can find something a a well stocked fly box to immitate.


One other possibility is that one is the dun and the other the spinner of the same species.

I know that they do change color a bit, particularly the wings, after mating.

Dave I'm sure your right on the 2nd it is a a dun just turned spinner and I would say it's likely a PMD


As you say both are mayflies.


Paul great Idea we need some stuff like this just to help in insect recognition.

The first one is a male Callibaetis, the second looks to be ephemerella - but without sizes it's hard to be sure.


Certainly isn't the same bug - since it would have had to change species and sex. :)

I tend mostly to go along with Scratch.

Two species, certainly two different sexes and a dun and a spinner.

From what I see in "Hatches" the first is a male dun, plain wing, small hind wing

(which may mean it's not a callibaetis) (can't see tails or guess length)

but from color etc, baetis is probably a good guess

The second is a female spinner, not sure how you classify the main wing, large hind wing

(so definitely not the spinner for the baetis) I'd guess size at 6 to 7 mm

to ephemerella is also a good guess.


Thanks to Paul from me also for putting these up and asking the question.

...never really thought about including the length of the bugs...


...picture #1, the bug is around 3-4mm in length...


...picture #2, the bug is around 6-7mm in length...


...hopefully this helps in determining the species of insect...
