the Yellow May or, Heptagenia sulphurea is the Big Bird of the aquatic insect world. not so much i guess in the big sense, but it has weird globular eyes, its yellow all over, can be seen from kilometres away, is undoubtedly the easiest ephemeroptera species to recognise and everyone loves it, specially hungry trouts !
here’s how to make a really nice one so you too can be in the Cool-Yellow crowd , enjoy !
