The Jelly Leg Colly (JLC) is basically Peter Carty’s Beadhead Coloburiscus nymph with Stretch Cord
legs | Size: 12 | Weight:
2.5 mm tungsten bead & lead-wire
Coloburiscus humeralis, or spiny gilled mayfly nymphs, are found in cool, moderately stable stony streams throughout New Zealand. The naturals feature
strongly in the diets of trout in many waterways, and good imitations are so different to regular patterns they are often the undoing of educated fish.
Coloburiscus nymphs have very robust translucent
legs that appear even larger and more translucent on account of a fringe of fine hairs used for filter feeding (see image).
Viewed from below, with the light
passing through them, they are likely to glow.
Glowing brown Stretch Cord legs have such an impact on the overall underwater appearance of the modified
imitation I named it the Jelly Leg Colly.
