    Default Wing Morphology

    Wing Network morphology came up in the "Why Treatment Free" thread.
    I prepared a number of wing scans to look at this typing approach.

    Ten wings from a hive with "Ukrainian queen" genes.


    The "cubital ratio" (which is the ratio of segment lengths on the middle window) is 3.06 s.d. 0.23, which is at the extreme upper end of the Apis mellifera range.

    The "DrawWing.org" reference wing for Apis melllifera carnica


    The DrawWing image has a cubital ratio of 2.73

    A comments, the Discoidal angle -- used as a primary axis for detection of AMM depends on the precise location of two points along an wide obtuse curve and the precise location of a single nearby broadly intersecting point to extend a very much longer perpendicular. This value is thus highly error prone since both small shifts in the baseline angle and small shifts in the intersection of the erected perpendicular would move the value.

    Modern papers use a 18 point network with 3 axis principal component analysis of the relationships among the larger network. I haven't yet imported this much expanded data set or tried the PCA.

    An Italian x Feral hive has wings, a sample (n=10) yielded a "Cubital Index" of 2.24 (SD 0.23):

    This is fascinating. But can they use this method to identify different breeds of Apis? If so then maybe I can identify what strain my mutts came from.

    interesting jwc. is it possible to differentiate mellifera subspecies other that scutellata using wing morphology?

    you beat me to it. i have the same interest regarding my mutts.

    Two papers seem very useful, both open access:

    Francoy Identification of Africanized honey bees through wing
    morphometrics: two fast and efficient procedures* Apidologie 39 (2008) 488–494
    (( despite restricted title, this presents wing morphometric data for all commercial races in its online appendix)
    http://www.apidologie.org/articles/a.../05/m07145.pdf

    Second paper is
    Bouga, Maria. A review of methods for discrimination of honey bee
    populations as applied to European beekeeping
    Journal of Apicultural Research 50(1): 51-84 (2011)

    Wing morphology is many possibilities for error.

    yep. dna testing would yield a more satisfying answer as to what these feral derivitives are, but i don't think it's readily available.

    In the first link there is a picture of a bee wing (page 491), and the different joints have each a number (1-19)

    Cubital index is the relation of the vein lengths 14-17/17-18

    There is apparently a distinct difference in the hindwings of Apis Mellifera and Apis Cerana (just in case anyone is interested). This picture originally came from Museum Victoria (Australia) http://padil.gov.au/pests-and-diseas...t/Main/135533/

    When we had an incursion of Apis Cerana in the far north, droppings from the Rainbow Bee Eater bird were examined for wing morphology of that species, to determine if they were in a particular area.
