[Note Guidelines] Photographer's Note
Eristalis pertinax is one of the larger hoverflies and mimics the Honey Bee, Apis mellifera. Often confused with E. tenax and E. similis, but on closer examination, E. pertinax has an entirely orange front tarsus (unlike both of the other species) and the hind tibia is pale in the basal half (unlike tenax).
Distribution: This is a common and widely distributed species throughout the UK; in fact it is often the most abundant hoverfly wherever there are suitable flowers.
Flight period: March to November, with peaks in May and August.
Behaviour: Visits a wide range of flowers, very often in company with the very honey bees it mimics. The males commonly hover in woodland clearings, aggressively defending territories as small as a few metres square. (UK Nature)
--------------------------------------------------------
L'Eristale opiniâtre (Eristalis pertinax) est un diptère de la famille des Syrphidae. Les éristales ressemblent aux abeilles, mais comme tous les diptères (mouches, moustiques…), ils n’ont qu’une seule paire d’ailes, contrairement aux hyménoptères (abeilles, guêpes…) qui en ont quatre. Contrairement aux abeilles qu’ils imitent, les eristales ne piquent pas.
L'éristale opiniâtre se distingue des autres eristales par les tarses des pattes antérieures et médianes qui sont jaunes. Seul le premier segment de l'abdomen présente un dessin jaune orangé. Les autres segments sont noirs avec une fine ligne claire.
Ce syrphe commun se rencontre presque partout de mars à novembre. La larve vit dans les eaux stagnantes et les fosses d'aisance. Elle a la forme d'un ver à queue de rat.

Hi Catherine, great composition with beautiful hoverfly and elegant flowers, fantastic colors, fine details and excellent sharpness, very well done, ciao Silvio

This is not E. pertinax. Pertinax has yellow front tarsus. I cant see which Eristalis it is. Probably tenax
