PLANTS/ANTS INFO NEEDED

Bryan,
Several times I have come across references to ants taking seeds of violets
and other plants into their nests (from wherever they happen to find them), supposedly to
eat some part of it. In the case of Viola species, there is an oily attachment (called an
eliasome) which serves this purpose. This obviously accomplishes dispersal for the violet,
so long as the seeds germinate - and one aspect of the theory is that by taking the seeds
underground, the ants save the seeds from being seen and eaten by birds etc. and provide a
bare patch of earth relatively free from vegetative competition. But there seem to be quite a
few provisos, which I have not heard adequate explanations for - like the seeds not being
buried too deeply. Personally, I also can't help noticing the similarity of the eliasome to
ants' 'eggs' or pupae - you know when you damage an ant hill how keen the ants are to
move the exposed 'eggs' back under ground... I have tried placing eliasome-bearing Viola
seeds in ants' paths but have not yet seen one pick it up and run off with it. But other
colleagues say they have.
If you discover or confirm anything to do with ants and violets, please email me; thanks.
