From the UV magical mystery tour

Food for thought...

Article just out this morning on some new research conducted into hummingbirds' ability to use the UV spectrum to distinguish food sources... They also used expensive filtering equipment to take pics of foliage and... plumage. Might be interesting to see the pics of the plumage. Sure wish they had photographed aquatic insects...

One thing they also learned was that green leaves have different intensities of UV on their tops and bottoms. The scientists hypothesize that this might help the birds navigate better through dense foliage.

Translating to trout, I suppose UV might help both identify food and navigate a stream bed. All rank speculation, of course. But now we know that the hummingbird, which shares with trout that fourth UV color type of receptor, can use UV color differences to distinguish edible objects from otherwise identicle non-edible objects. 

To my mind, this suggests that matching colors of a fly pattern to the naturals might yield better results if we could match the UV characteristics of our materials to that of the real bugs. All it would take is getting them to use those $10,000 UV photo filters on fly tying materials and on aquatic insects in various life stages...

If you're trying to save money tying flies for fishing ... the UV filters to check your materials will pay themselves off by 2094.

Out on the river the other day, I was watching hummingbirds grab caddis out of the air. That was pretty cool

Oops. My bad. Can Google Cynthia Tedore (the scientist) and hummingbird for other sources of the current news.

Very cool.

One fly tying writer (Allen McGee) says mayfly wings and head have UV and that Caddis fly bodies have it. He speculates the diving Caddis use their non-UV wings to hide their UV bodies.

https://books.google.com/books?id=KIQRDQAAQBAJ&pg=PA51&lpg=PA51&dq=soft+hackles+caddis+wings+mayfly+body+uv&source=bl&ots=Pzvazv_ZiZ&sig=ACfU3U0nmYWwwHAU3tFyJhf-bmkaaqM7aQ&hl=en&sa=X&ved=2ahUKEwj6naqdrM3qAhUPeKwKHTatB6UQ6AEwCnoECAEQAQ#v=onepage&q=soft hackles caddis wings mayfly body uv&f=false

If that's right (UV body, non-UV wings), a fluttering Caddis fly might look like a flashing strobe light to the hummingbirds

This falls under the heading interesting but not applicable to practical fly fishing.

i fish for fish not hummingbirds 😀

Reminds me of when I was kid. At night we'd circle cast flies in the air to try and get the bats to take 'em. Never did have much luck

hi have you tried clear antron in the thorax of your nymphs or dries garry lafountaines sparkel emerger and deep sparkel pupa where the result of 10 years researce into caddis flies and were very sucessful river patterns so if you adapt your patterns on the same pricipal will reflect both UV light and the colours the flie is tied with hope this helps experiment

kind regards Steve

I agree with you to watch hummingbirds grabbing bug while in flight is pretty cool I was on the upper bear creek suppose to be fishing spent more time watching the hummer fun to watch
