Female Notch Horned Cleg

Dear Kevin,
Though we were confident that this is a female Horse Fly in the family Tabanidae, there were enough features to cause us to consider it might be a member of a different family, but we quickly located the Notch Horned Cleg,
Haematopota pluvialis, on Influential Points  where it states:  “The female Haematopota pluvialis has distinctively patterned hairy eyes – the eye stripes extend over most of the eye.”  The site also states:  “There are of course innumerable accounts of Haematopota pluvialis biting man, especially in upland areas where clegs can turn a pleasant walk into an endurance course. Our own experience in the Scottish Highlands is that when the sun is out, the clegs bite; when the sun goes in the midges bite! Flight (and hence feeding) activity of Haematopota pluvialis is dependent on a sufficiently high humidity and temperature (Krčmar, 2004).”

Yes! That’s it, thank you! In Dutch it appears to be “Regendaas”.
