Cross-species matings

April 9, 2003
From: Bill Rudman

To accompany Atsushi's message, on two species of Halgerda apparently mating, I have prepared a Page where I will list any messages on the Forum which deal with apparent matings between species. I will also include similar interactions, such as two species of Risbecia trailing, which also suggests some breakdown in either our concept of what is a species, or the species ability to recognise its own kind. There are three in the list at present. If I have missed any, or if anyone as further examples please let me know.
Best wishes,
Bill Rudman
