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

Thank you Theo !

Could you tell me where to find some information on the biology of this species? I have been searching the web, but I didn't find much.

Thanks in advance,

Tjitske

I am not sure what you mean with 'biology'.

A taxonomical review is due to yours truely (Zeegers 2005 in Studia Dipterologica). The larvae are very little know (only from USSR species, in Andreeva). The males hover persistently at 1 meter altitude. Seguy and Zeegers (2005) give the review of the records in France. Otherwise, little has been published....

Thank you Theo. That is what I wanted to know. Something about the life (where do the larvae live, what do they eat, etc...). I understand that little is known about this Tabanidae.

What word do they use in English, talking about the way of life of a species ? Maybe they use ecology ? In French they use 'biologie' I far as I know.

I am sorry I can't find your article though...

It is in Studia Dipterologica, or on my researchgate.

Hi, Theo

I couldn't find the paper among articles uploaded to your profile at RG. Would be great to have a copy!
Cheers,

Hello, I'm having a problem posting new threads, as the "No new Threads allowed..." is showing up on all of the forums. Is there some sort of thread limit I've exceeded?
