I have noticed a decided difference in UK chironomid pupa construction from the West. UK patterns are sleeker, seldom bead headed and often possess the addition of a ‘wing bud’; almost its own attractor it would seem. I have experimented with this a bit. A couple good midge sites (buzzer, chironomids, gnats)

 “Slim buzzers are really important: the creatures you are imitating are not bulky at any point of their anatomy – so why should your artificial one be so? Secondly, pick a target feature to incorporate in your dressing. In most buzzers the wing bud is quite a distinct feature in the natural, so many fly-tiers emphasise this element. I believe I told readers about this a few weeks ago when I was going through some early season patterns. I use “Tulip T-shirt” paint to get my buzzers with a target spot, but there are many other bits and pieces used. One of the most common materials to get this wing bud effect is a slither cut from a “Walkers” chicken flavoured crisps packet, whilst other tyers use a couple of turns of fluorescent floss silk.”
