Blue-winged Olives

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Got an Olympus Stylus710 as a gift and have just started playing around with it. Here are the very first pics I've taken.

Nice pics, Spud. That high-gradient mountain stream looks a lot like one I was on this weekend, but in a different state.

Your unidentified mayfly is interesting to me. Is is missing left wing(s), or is that only an illusion? Did it have hind wings? What would you estimate to be its size or length from front of head to end of abdomen? How many tails did it have?
Best regards,

It had both of its wings and no hind wings, I am just a poor photographer ;). I am short on time right now but will resize and add some more pics shortly. I will measure my rod tas well to try to get you an accurate length measurement.

Nice pics Spud and you do look pleased with your brookie.
Did the Mayfly crawl or fly onto your rod?
