      Is anyone currently doing any DNA research with the two cryptic species Halictus ligatus Say and Halictus poeyi Lepeletier?  If so, I have a specimen set that might be of interest to you and might benefit you as well as me.

       

      In 2009, I conducted a yearlong bee bowl survey on Hart-Miller Island in the northern Chesapeake Bay.  I ran one 20-bowl transect in each of six habitats on 18 sampling dates.  As part of that effort, I collected 410 specimens of H. ligatus/poeyi that ranged over time from 4 April to 29 November with three collection peaks on 19 May, 7 August, and 21 October.  The sampling date data are as follows:

      I would be interested in knowing whether one or both species occur on the island.  If there are two species, I would be interested in knowing if the species show any temporal or habitat partitioning.

       

      If my specimens might be of interest to you, please contact me.  Thanks.

      Greetings

      Attached is the original paper  noting some aspects of the distribution of these two plus another one that compared phenology from Rock Hill, where they occurred symaptrically - alas, almost identical patterns.

      An update based upon more genetic data was published in the Byron Alexander memorial volume, from the natural history museum, univ. kans.  At that time, the most northern record of poeyi was from Williamsburg Virginia, with ligatus occurring in DC, Natural Bridge, Fancy Gap and Nettleridge Virgina.  Given global warming, the possibility that ligatus is being replaced (or added with) poeyi in some parts is possible (they are sympatric in many places but I did not find them together close to you, but did find them together in NC.

      I do not have this as a pdf, if there's interest I can arrange to get it scanned?

      Hope this is of some interest.  Unfortunately, I know of no morphological way of differentiating them, though people have tried - even morphometric data did not separate them well.  They are very divergent genetically though.  It's an interesting problem.

      Perhaps someone on the list has found some morphological means of separating them?

      cheers

        All:

        I have seen Gene's specimens and I think they are more likely H. poeyi than H. ligatus....

        Although it remains untested molecularly, I have looked at the extreme ranges of the complex and think that H. poeyi has different proportions to the clypeal sutures than H. ligatus that go beyond differences in F1 vs non F1 generation specimens.  Males are not so clear, but may have more pitting on the rims of the tergites in H. poeyi.

        I also think H. poeyi is more of a sand specialist than H. ligatus and that it could run well up the East coast in sand areas.

        It would be nice to test out my suppositions with molecules!!!!!

        Landscape With The Fall of Icarus


        According to Brueghel
        when Icarus fell
        it was spring


        a farmer was ploughing
        his field
        the whole pageantry


        of the year was
        awake tingling
        near


        the edge of the sea
        concerned
        with itself


        sweating in the sun
        that melted
        the wings' wax


        unsignificantly
        off the coast
        there was


        a splash quite unnoticed
        this was
        Icarus drowning


             - William Carlos Williams
