Today I found this enormous Tabanidae on Heracleum sphondylium (Hogweed). Never seen anything this big, must have been at least 20-23 mm, probably more. First thought was a very large Volucella (Syrphidae), but soon after I found out it was a horsefly. I suppose it must be a female Therioplectes gigas? There was a second one but I could not see if this was male or female.

Thanks in advance for any information about this spectacular species, Tjitske Lubach
