So partridge pea sets out a buffet for a number of insects that it doesn’t need in order to attract some ants that it does need.
So how do these insects find the extrafloral nectaries? I smelled a few of the stems–there was no odor that I could detect. Flowers give visual clues for the presence of nectar. I can see nothing of that sort on partridge pea stems.
The snout clearly seemed to know that something was there. So did most of the flies. How do they know?
Any ideas?
