Index of Subjects <html> <body> Thanks again to both of you. In terms of photos vs. collecting, my prime aim is to photograph the beast. Usually by that time (especially Hover Flies!!), they are gone never to be seen again. However better photos may help.<br> Angus<br><br> At 11:08 AM 9/2/2006, you wrote:<br> <blockquote type=cite class=cite cite="">Hi Dave,<br><br> On 2-Sep-06, at 10:12 AM, David & Alison Webster wrote:<br><br> <blockquote type=cite class=cite cite=""> <i>E. tenax </i>as illustrated in Swann & Papp has a dark, squat wineglass figure, & distal to this, a thin pale band on visible tergite 1 and insect length is given as 0.6". I have two numbers (A212 & A218; 15 mm & 14 mm long respectively) that compare well with Swan & Papp's illustration. <br><br> In contrast, in the photo taken by Angus, [what is it Jim Angus' photo or Angus's photo ?] the dark area in tergite 1 is shaped like a broad vase and has no pale distal band. My A325 has a similar dark area on tergite 1 and is 10 mm long. <br><br> Based on the above I still lean to <i>Eristalis</i> but rule out <i>E. tenax</i> and would guess Angus' yellow flower, which I don't recognize, to be about 25 mm wide. In some situations a specimen is worth a thousand pictures. </blockquote><br> We have a large number of specimens of <i>Eristalis tenax</i> at the Museum and they exhibit quite a bit of variation in colouring. Its the only large <i>Eristalis</i> that we have specimens from in NS that is comparable to that pictured in Angus' photo. On the other hand, there is no guarantee that all the specimens we have at the Museum are correctly identified, so it is possible that there is more than one species amongst the material.<br><br> Cheers!<br><br> Chris<br><br> <font face="Times, Times"> _._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._.<br> </font><br> <font face="Times, Times">Christopher Majka - Nova Scotia Museum of Natural History<br> </font><br> <font face="Times, Times">1747 Summer Street, Halifax, Nova Scotia, Canada B3H 3A6<br> </font><br> <font face="Times, Times">(902) 424-6435 Email <c.majka@ns.sympatico.ca ><br> </font><br> <font face="Times, Times"> _._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._.<br> </font></blockquote></body> </html>
