Blog, news and reviews from Snowdonia Fly Fishing Guides
The hawthorn fly (Bibio marci), heather fly (Bibio pomonae) and black gnat (Bibio johannis) Hatches of these terrestrial flies are fairly common here, though short lived. The first to appear in the spring in the hawthorn, or St Mark's, fly. Some years the hatches can be spectacular but seem to have diminished over the last few years.
Next up is the heather fly that usually put in an appearance, but in smaller numbers, in the middle of summer. They are just as ungainly in flight as the hawthorn fly, but are usually a little smaller and have strikingly red thighs.
Black gnats can be seen in spring, summer and autumn sometimes in impressive numbers and locally I see the biggest hatches in late September and October.
They are all an important food source for trout and grayling as they are often blown onto the water, singly or sometimes in pairs, joined in mating.
