Photo taken yesterday. Could it be some blackened form of Episyrphus balteatus? Thanks! |

Hello chickenold, This is indeed Episyrphus balteatus. The amount of black is dependent on the temperature during pupation. This is an inter-sex specimen with features of male and female strangely combined. The eyes are apart, but more closely then in a true female. There is also a bump on the tip of the abdomen, but not true genitalia of a male. For a comparable tread: http://www.diptera.info/forum/viewthread.php?thread_id=43483&pid=190611#post_190611 I do not know if the darker colouration is due to the temperature or the specimen being a mix of two sexes.
