One of our most common and familar flies


Lucilla caesar: the greenbottle

Post date: Monday, 22 February, 2016 - 00:00

So flies are not everyone's favourite creatures but, even if you despise them, just take a moment to have a close look at the greenbottle (Lucilla caesar). The shiny metallic green colouring is, in my view at least, amazing. You can even see my reflection in this one as I creep up on it to take its photo! Look at those amazing big brown eyes too, nearly 10% of this insects body are eyes. 

Great sunbathers on walls and fences the greenbottle rarely comes in to our houses and I confess that it is not the most tasteful of insects. Frequently seen on dung of all kinds, especially dog's, and then seen on blackberries. Do you like to pick the odd blackberry to eat as you stroll along a country path?  It lays its eggs in carrion and the larvae, we know them as maggots, are a key part of the recycling process.
There are various similar species but, as far as I can tell from the pattern of veins in the wing, this is the commonest, Lucilla caesar.
