For the past week or two reports have been posted about sightings of Gray Foxes, Invaria, (spring sulfurs), and Isos. Yes, I've seen a few Gray Foxes and Invarias on the freestones but nothing that would constitute a hatch occurred where I was. Thursday in the lower WB the hatch was of Hendricksons. As to the Isos, I have seen none. I also haven't seen the big hatch of dragon flies that precedes the hatch of the aforementioned bugs by a few days, (the dragon flies feed on the big mayflies).
On my drive home Saturday morning I saw one small roadside patch of Ragged Robin, the precursor of the Drakes, that lines the interstate ditches with pink blooms during the drake hatch. Let me remind you that we had a very cold winter with ice covering the river system except for the very top of the tailwaters. Yes, we had a burst of warm weather in April and last weeks 90 degree days, but this weekends weather has been more the norm.
We will most likely still have Hendricksons hatching after June 1st up in Deposit. As for the other bugs, I would expect them all to be hatching within the next two weeks. If I've managed to miss significant hatches please let us know. With the high water on the BR, Thursday was my first venture there. Downriver floats may well have encountered hatches of all the bugs making their way up river.
Strangely, with the mayflies a little behind schedule, the caddis hatches seem to be on or even a little ahead of schedule. Have seen the prolific apple caddis hatch march up and out of the river system and ran into the blue sedges this past week on the freestones.
My Jim Dygert endorsed Tackle-Pac vest has the pockets crammed with almost every fly box I own in anticipation of what's to come.
Update - Received a call from Rick, the owner/manager of the Syracuse Troutfitter branch, to let me know that there was a good March Brown / Gray Fox hatch this afternoon on the UEB. Go Figure.

Yesterday I saw the same color of dragonflies that Ed Smith saw on the BK. Also had a nice caddis hatch in the am size 18 gray.
The rest of the day was a dud, very little bugs where I was. Maybe the spike in flows on the freestones put them off?
A119 thanks for the report and Ed S -The DC5 👍
Angler 119- Thanks for the report and some more insights on natures signals. I encountered a heavy hatch of green metallic dragon flies on Wednesday on the lower BK. I was sitting on the bank and they were on my waders and in the weeds drying their wings. Did not realize they were the precursor/signal of future hatches. Thanks again . By the way —I like it like that.. Ed
👍 thanks for the report
