Hi flyforum * locality - Silgueiros - Viseu - PORTUGAL * date - 2007.08.16 * size - 5 mm * habitat - openland * substrate - Mentha sp. flower I testified two great moments. I saw twice two conopids piercing two wasps very quickly. In less 1 second. Moreover, the wasps/bees were feeding on Mentha flower, so piercing can be done even with wasps/bees feeding not just during the flight. The wasp and the bee tried to respond immediately, but it seems that conopid got the wasp... I could catch just one wasp. (i will photograph it more later. ) If I recall well Zodion spp. attacked the bee. The other conopid that I will show more later attacked the wasp, if I'm not wrong. There were plenty of bees/wasps/flies (tachinids flying very near ground as well). I saw many conopids around. I think that is Myopa sp. but not M. picta neither M. occulta.  What called my attention were two things: thorax striped, and tergites (in anterior part) are spotted with black dots. The proboscis is not so long as it happens with M. picta. it pointed almost above antennas. I will give you more photos more later and some more info about the fly.  i suggest that you take a look here to see it bigger: http://www.flickr...142&size=o then:  to see it bigger: http://www.flickr...479&size=l more images, more later. (I have lateral, dorsal and posterior views of this fly.) EDIT---> Title changed from "grey conopid  - Myopa sp. - not picta neither occulta " to "grey conopid - Zodion sp." then "Zodion sp. Perhaps Z. cinereum?" then to "Conopidae - Zodion cf. cinereum?" to "Conopidae - Zodion cinereum"

I think it is a Zodion, not a Myopa. The proboscis is not folded back.

and you must have reason. Chris told me that if this was in UK it would be a Zodion sp.  Ok. For now I will change for Zodion sp. |

According to Van Veen's key : "1.a. Legs blackish, femora partly pale; anus black; antennae black or 3rd segment reddish -> 2 1.b Legs reddish; anus red; antennae red -> 3 2.a. Antennae black; wing: cell R closed far before wing border. 4-5 mm. NL, B, D -> Zodion notatum Meigen 2.b. Antennae partly reddish; wing: cell R closed near wing border or just open. 4.5-9 mm. NL, B, D -> Zodion cinereum Fabricius 3.a. Abdomen with depressed dots, greyish dusted; wing: cell R open. 7.5-8 mm. D. -> Zodion carceli Robineau-Desvoidy 3.b. Abdomen without depressed dots, reddish or yellowish; wing: cell R closed. 6-9 mm. Middle and Southern Europe. -> Zodion erythrurum Rondani Literature" This must be Zodion cinereum. Do you agree?

Cell R closed very near wing border (look 3rd image). Antennas are partially red.. Anus black. Very strong probability to be Z. cinereum. What do you think? Edited by jorgemotalmeida on 17-08-2007 22:35 |

Great Photos Jorge. I have never seen Zodion, so it is good to see what they look like.

According to David Clements, the ID confirms. Zodion cinereum. |
