It fits very well. I saw 3-4 Sphingidae around. I found Macroglossum stellatarum. |

Theo, the Frontina laeta that appears in gallery is not so golden.. are they variable in colour? |

This is a female, in the gallery is a male. That explains a lot. Theo |

ah! yes! thanks. Is it just the colour that enable us to distinguish between male/femle of Frontina laeta? It is a good way and quick to split them! |

The length of antennae is even bigger i male. Moreover, in nearly all cases in Tachinidae females have 2 additional pairs of proclinate frontal setae, which males don't. Any specimen with elongated claws is bound to be male. Theo |
