Hello, is it "more or less" sufficient to look at the size of calypters: - both have same size: Anthomyidae - lower is larger: Musciudae? Can I get a solid hint? Regards Lothar |

Regards Lothar That is usually true. There are a few Muscidae with small lower calypters (subfamily Azeliinae, some Coenosiinae) and a few Anthomyiidae with large lower calypters, but not as large as Musca or Phaonia. You can also look at the hind tibia. Very few Muscidae have 2 or more posterodorsal bristles, and very few Anthomyiidae have fewer than 2. On the thorax, the very few Anthomyiidae with 4 postsutural dorsocentrals have many more hairs on the thorax than similar Muscidae. Very few Anthomyiidae have hairy eyes. If there are any Drymeia with 4 postsutural dorsocentrals they may be confusing. |

Thanks… can you be so kind to specify "hairy eyes". I am just amateur, layman, beginner. Reading a bit about Chaetotaxy revealed that hairs near the eyes are: - occipital hair - fascial hair - subvibrissal hair - parafascial hair - … where to look at? Lothar |
