As Dave has reminded me of Clearwing lures, I tried out my VES in the garden yesterday hoping to get Yellow-legged which has alluded me so far. It still has, but a single Orange-tailed did appear. I've had these before and this one didn't linger so no photo I'm afraid.
I do wonder what the shelf life of these lures is. The ones I am using must be at least 5 years old and I use them every year usually with some success. Storing them in the freezer as recommended obviously helps, but I keep thinking I should renew.
