Well, it's Tachinidae, so I think we are all waiting for Chris or Theo

I have been studiously avoiding this one because it's just not something I can recognise easily. Early species are few and far between but I seldom come across anything but the usual Gymnocheta or Tachina ursina here  The very hairly eyes, bare parafacial and slightly unusual arrangement of scutellar bristles should be fairly characteristic but if I was going to venture an ID I'd prefer to see the specimen because there's not enough visible to allow me to key it  |

It's Cyzenis albicans no doubt, a rather early spring species in deciduous forests, quite common. You can see that there is one (pair of) proclinate orbital setae, which is very unusual in Tachinidae: the rule is none in males and two pairs in females. However, in Cyzenis both sexes have one pair. That's why the genus was called Monochaeta for long time. Theo |

setae are bristles - which are the orbital setae ? |

Look at 'glossary' under 'navigation', that's why I don't bother to explain it in every post. Theo |
