Female judging by the eye spacing
Thanks Michael. I didnt know about the eye thing for determining gender.
In general, with big eyed flies such as hover flies and horse flies, the sexes can be distinguished by the eyes; in males the eyes almost touch with barely any spacing, at least near the top, but in females there is a noticeable separation. It's easier shown in pictures than with a description!
But then there are those hoverflies like Helophilus where both sexes have separate eyes!
My Flickr photos...
Hence why I said " in general". A "slight Inaccuracy can save pages of explanation" was phrase one of my former bosses used.
He clearly wasn't an entomologist...
He wasn't, but then he would refer to them as "Boffins". Still, the principle that you can overwhelm people who have little knowledge with too much information so that they lose interest is one to remember.
Nevertheless a good comment.
Perhaps I should have said "sometimes" rather than "in general"
To be honest, I think that the vast majority of people on iSpot love those extra pieces of information which they don't get elsewhere, as so many places on the internet/general insect books are dumbed down or just patently inaccurate. :)
Not wishing to prolong this but ophrys' last remark is much appreciated. If there was a "Like" button on this site I'd press it for that. Paul
