My son reared 2 Syrphid larvae, one male Meliscaeva cinctella and 1 female Meliscaeva auricollis, but both were in the same jar. Does anyone know which pupa belongs to which Syrphid? Or is there any literature on pupae of Syrphids?    |

Hi Paul, I do not know literature on the pupal state of syrphids - for the larvae I use Graham E. Rotheray (1993): Colour Guide to Hoverfly Larvae. He says M. auricollis larva's prp (the posterior breathing tubes) has a basal rim while M. cinctella's is yellowish brown in overall colour. Your darker larva is not unicoloured and seems to have a basal rim so I guess this could be M. auricollis. Greetings, Eric K |

Thank you for your reply. I have some difficulty in distinguishing the basal rim, I have made detailed pictures of the 2 pupae breathing tubes, first photo is of the dark pupae, the second of the light pupae.  |

Yes, there's hardly a difference between the pupae. Remains only the colour/pattern - but I'm afraid it's not enough to identify.
