Stony Stratford, Bucks (UK), 22nd September 2010. On old wooden fence below willow, ash and sycamore. Grazing cattle and water close by. Would appreciate help with identification (unfortunately this is the only pic I have so no dorsal view): Bruce

Could anyone tell me what separates Suillia affinis from other Suillia species? That is, what is specific to this species which other Suilia sp. do not have. I find Bruce's fly looks different to the one I had which is also S. affinis, the main differences being the bristles on the hind femur and the many bristles on the ventral area between legs 1 and 2. Could this be a difference between males and females? I'm trying to learn what I should be looking for so would appreciate any help with this. Janet

It is not possible to give 1 characteristic, which is affinis separating from all other species of affinis. It is rather a combination. Affinis is rather common. the sides of the thorax (mesopleuron etc) is bristle-free. the arista of the antenna is long plumose the animal is fairly large, but as large as gigantea, which is 9-13mm. Affinis is between 5-9mm. In order to be sure it is not umbratica I check the colours of the bristles on the back-side of the head near the neck. If they are yellowish it is affinis. ruud van der weele rvanderweele@gmail.com |

Janet, try to get the key of P. Withers. Proc. Trans. Br. Ent. Nat. Hist. Soc. 20, 1987. It is very handy and it will be quite easy to separate the common species of Suillia.

Thank you Ruud and Andrzej! That is a good start to my learning about these, I will see if I can find the reference works mentioned either online or secondhand books listed online. http://cubits.org... |

Well, I found the one you mentioned Ruud, but there's a full bound set from 1952 to 2001 of 50 volumes. If anyone wants to spend £250 I would say it's a good find! Item no. B1907 http://www.pemboo...sed01.html Alas Andrzej, I only found the first edition of The Insects of The European Part of The USSR, both in Russian and translated versions. It would be good to have that too, and the cost is not so bad but too much for me. Someone else might be interested though, from Abe Books. http://www.abeboo...7&y=19 (got the wrong link) Edited by blowave on 01-10-2010 15:13 http://cubits.org... |

phil withers wrote: I'll see what I can muster... If it's not too much trouble, thanks! I have just snipped 56 pages from the keys on google books, of course some of it overlaps. I need to trim off the unnecessary stuff on the pages, they are copied to my Pictures location in jpeg so I can place them all in one folder and view in succession.
