hi all, ..as usual it's one of sd's threads I arrive at whenever I need to look up a new fly, so thanks Steve for chopping down all that wood! My specimen has hairs reaching about two thirds of the way along that 'sub-costal' area, but no red patch on the side nor any trace of red on the scutellum. The parafacial area is blueish. Is that still ok for heraclei? I keyed it together with a small vulgaris and the differences were very clear, and it took an unusual route through the key, sending me back to couplet 35 from 101 best wishes, Jeremy |

I'd need to see it really - if it is a male then the genitalia can be useful to confirm heraclei. The 'subcostal' bristles feature is difficult because Belshaw named it incorrectly in the book and you are often looking for only 1 or 2 bristlets and one wing can have them while the other wing doesn't

there are six hairs on one wing and three on the other, on the underside of the wing-edge beyond the costal spur. Fig 394 shows nine hairs on this area. |
