Alainites muticus/Nigrobaëtis niger - Iron BlueNigrobaëtis niger (formerly classified as Nigrobaëtis niger) and Alainites muticus (formerly classified as Baëtis muticus) are very similar and share the common name of the Iron Blue. The iron blue dun is much darker than any of the other common upwinged flies. Its nymph is an agile darter and occurs on chalk streams, spate rivers and fast-flowing brooks. The dunThe dun emerges at the surface in open water, and hatches can be fairly dense even on sunny spring days. Specific imitations have been devised, but a general pattern is often acceptable in the rough and tumble of a spring river. The spinnerIron blue spinners lays their eggs in the afternoon, and so they are useful flies to imitate. The differences between the sexes are quite marked. The female (above) is sometimes called the Little Claret Spinner, while the male (shown below) is the Jenny Spinner.
Footnote: Baëtis is often written simply as Baetis (without the accent on the e) but as this is the scientific name given to a genus the capitalised form Baetis is used rather than baetis. |
