Hello!
Why would ants (Messor sp.) gather pieces of starch, both with vegetable oil and without, food supplement?
From time to time I see an ant getting a piece and hauling it inside the colony, so far I have only very limited ideas about - why that is happening. 
*I used starch and vegetable oil as a barrier until I got some talc, in case you wonder why that's there.
Hope you all have a great time!
