    Default E. acroleuca apicalis?

    Shot this Banana Skipper in CCA. The butt was frightened either by the flash or the shutter sound, resulting in a shot showing the butt taking off from its perch. Camera settng was ISO3200, 1/125, f5.0.

    The upf has a white apical patch. Could this be Erionota acroleuca apicalis? Or simply a worn specimen of the other Erionoto spp.?

    These buggers are difficult enough to ID in a collection, much less a field specimen! But from the spots and the whitened wingtip, I would concur with your ID, though we will never be 100% sure.

    However, please note that the correct name should be Erionota hiraca apicalis. If you look at the first few pages of C&P4, there is a loose sheet titled Addenda and Corrigenda. Reference is made to Plate 58 Fig 20 where the correction of the name is mentioned.

    Thanks, Khew for the ID "confirmation" and name correction. Agreed that with existence of many look alike Banana Skipper species, and factor of wear-and-tear, ID with 100% confidence on such field shot is not possible.

    Very good noise handling at ISO 3200, nevertheless.

    I did some cleaning up of noise during postprocessing for this shot.
    Sunny made quite a few shots of other butts at ISO3200 too. Hopefully we will get to see these shots later on.

    Dug out this thread which I missed while doing forum search on Erionota hiraca apicalis

    This must be the late...st reply ever in BC .... 2 years 6 months


    Went back into my archives and reviewed the 31 Aug 07 file and found that I had shot 2 on that day, one of them with Horace.

    According to C&P4 ID keys for the separation of the species of Erionota ...

    4. Male upperside forewing apex prominently whitish. Antennal club entirely white above . E. acroleuca ( meaning Erionota hiraca apicalis)

    The first shot is of the same individual as Horace. This shot clearly showed the white antennal club.

    #2

    ISO3200 1/30s F/9 FF HH Canon 40D



    Anthony ,

    When confirmed please add to checklist , though not the best... at least it would not be left empty........ and another Plus 1 from my archives

    Sunny, better late than never.

    Ant, we can never be 100% sure that it is E. hiraca. But then again, no one can 100% dispute us that it isn't E. hiraca either. So put Horace's and Sunny's first shots into the checklist.

    Also, regarding the checklist, it's a question of presentation. If we don't have a good shot with a confirmed ID of the species, there is no need to put such a BIG questionmark to represent the species. Just leave it as a unobtrusive black box so that it doesn't call attention to the fact that we don't have a shot of the species!

    See what I meant : After you get your +1 , all of them start appearing from nowhere!!

    These two demanded to be shots keep buzzing me in the shade and landing right in front of me.
