[leps-talk] MALE x FEMALE emergence

[Nigel Venters]

Here's a shot at it!

In many species males usually hatch first as their claspers and aedeagus need to harden fully before they can mate successfully..often a few days...this  allows some dispersion to take place to reduce the chance of pairing with a female from their own brood.

Maybe in gregarious species...as there is a high concentration of the same brood in exactly the same place...nature by allowing the females to hatch first causes an even further dispersion to occur before the males from the same brood to hatch, mature and start to pair, thus making it unlikely to pair with a sibling.

  I using this post to start a new trend.

  In my experience, breeding highly gregarious species of leps (the type that eat together, rest together, pupate together, etc), it always happened that all females emerge in first place, with a window of 1-2 days of both sexxes emergence, and than the males at last.

  The bugs I've rear in these conditions are

  Euselasia eucerus (RiodiniDAE)
  Pereute swainsoni (Pieridae)
  Doxocopa zunilda (Nymphalidae)

  One exception is genus Actinote (males come first, BUT they give up gregarism at the last instars; by the way, generally MORE than FIVE!!).

  I bet Asterocampa comes with females first (voilá!).

  Does any one have a sugestion for this lep peculiarity??

  best wishes

    The guess big news on my May 16 trip was the discovery of C. gorgone at
    another site.  This colony is 15 miles from the Clay County population I
    located last year at this time.   I wanted to check some new areas and
    arrived at this location in Macon County at 8:00 AM.  It is a  cleared
    narrow ridge crest at about 4000 + ft. (I forgot to take my altimeter).
    It is on private property and I had to cross a fence line to get to it (No
    no trespassing sign so in I went.)   About 8:30 there was enough sun and
    warmth to start bringing stuff out.   There were a lot of very strange
    monster Pearl Crescents (P. tharos) at this site (more on these later).   I
    was very interested in these and so way paying a lot of attention to them.
    Which is the biggest factor in why I noticed the female Gorgone.  It was
    very fresh as I stirred it from the grass.  I spent 1 1/2 hrs looking for
    more and saw none.

    I also saw another fresh female over at the first site in Clay County late
    in the day when I finally got over there.   The fact that another colony
    has been found along with the thin numbers  - both last year and this -
    indicates that this is likely wide spread (but local) in that region and
    that it emerges slowly over several weeks and thus "a bunch" are never
    found at one time.

    The habitat at the new area was similar to the Clay Co. site only that is
    was in primarily deciduous forest.   This new area is unfortunately in a
    rapidly developing area and the ridge top is such a great view it is only a
    matter of time till some wealthy person buys up the property, rips up the
    environment, and builds their dream mountain home.  It has a super vierw.
    Anyone want to help TILS buy this site?  Got to go.

    Ron
