Scientific Name: Eristalis intricarius
Common Name: n/a
Eristalis intricarius is a bumble bee mimic, with a range of colour patterns, it has the base of the hind femur pale-coloured, as opposed to Merodon equestris, another bee-mimic, which has entirely black legs and an apical ventral projection on the hind femur. Also note the dark, crescent-shaped markings mid-way along the outer edges of the wings.
As with all Eristalini, it has a deep loop in wing vein R4+5, and the upper and lower outer cross-veins form a virtually continuous line parallel to the wing margin.
Though not an abundant species numerically, it's fairly common throughout the UK March to November, peaking in late July. Comes to flowers readily but males can also be seen hovering some way above the ground. Frequently found on umbelllifers, such as Hogweed, and also Common Knapweed. Volucella bombylans is another similar fly, superficially, but has no U-shaped bend in the veins.
www.uknature.co.uk is a website dedicated to showing the immense diversity of UK nature and wildlife. Our vast range of habitats, from lowland arable to snow covered mountains, from storm-ravaged coastlines to peaceful inland freshwater lakes and rivers, from dry, sandy heaths to deciduous and coniferous forests, all these habitats contribute to the abundance of UK nature. We have wild birds in huge numbers either residing or visiting our shores (597 recorded species as at July 2013) and we must also not forget the humble back garden with its grass lawns, flower beds filled with nectar rich flowers, shrubs and trees, all designed to attract huge numbers of insects such as bees, moths, butterflies and hoverflies; and finally the small ponds which provide safe havens for frogs, toads, newts and even slow worms and grass snakes. www.uknature.co.uk is the showcase for my personal passion, photographing uknature in all its glory. I sincerely hope you all enjoy the fruits of my labours.
