I hope this image is of some use....a quick, single, spontaneous shot when the horsefly landed near me, camera settings were for some artistic photography of flora I had been busy with.
This horsefly may be genus Tabanus, based on sightings from other members and on line searches. Not enough other physical details to place specific species.
