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.
Thanks for the info Joe. I've not looked at any Partridge skins lately because I've a full skin already. I think my local shop has one or two on the shelf, and it would be worth knowing if their prices doubled as well. I will also be at Cabela's on Sunday, so I can compare prices.
As for a shortage, I have not heard of any, but I'm usually the last to know anything.
