    Next is an interesting harvestman.  Thanks to Dr Philip Bragg for identifying it, and congratulations to Ian Cooper for persisting over several nights in getting the photographs at Colquitz River Park.   Dr Bragg writes:  The latest set of photos are excellent. No single photo showed everything I wanted to see but together I feel fairly confident in identifying the harvestman as Oligolophus tridens – – a European import. Ian’s initial photo showed a trident on the front of the carapace and spines on the ocular tubercle suggestive of Oligolophinae. Later photos were not clear enough to be sure about this but the current set support the initial suggestion. The trident is quite clear in one of the photos showing the harvestman eating some carrion. The pattern on the body is typical of O. tridens.

   Another invertebrate that Ian photographed at Colquitz River Park is this nematoceran fly.  Not sure what it is yet.  Probably Tipulidae or Trichoceridae.  Most likely tipulid subfamily Limoniinae (sometimes treated as a full family, Limoniidae).
