Hello all - just had a wander around the back garden to see what was about in the hoverfly world - all the usual suspects were there, abundant E.balteatus and S.ribesii/torvus/vitripennis, again quite a few S.pyrastri (I've seen more of these this year than ever before) and a few S.pipiens ... and this little chappie, who I don't recognise ... anybody hazard a guess?  |

Afternoon Jez,
It's Dasysyrphus albostriatus, summer-generation.
Take care, Jason  |

After some research, I have a name to throw in the mix: Dasysyrphus albostriatus ... is it a possibility?  |

Yes, those 2 pale lines on the thorax indicate classic Dasysyrphus albostriatus markings. The abdomen spots can vary a bit.
When those lines are indistinct or hidden, this species can easily get confused with Meliscaeva auricollis. |

Yes, it is albostriatus, but doesn't the abdomen appear a little narrower than usual? Those I saw earlier in the year widened at the apical end of the first tergite before tapering down again, giving a bigger appearance. | | |
