They get pollen from crimson clover, nectar from vetch,those are probably gone this time of year. Saw a post the other day from Alabama where there were some bees on Bahia grass, would never of figured that. All depends on whats in the field on whether it is going to help either of you. Also may want to know what else is around where his fields are. May be a great place, check it out, if you would like.
Good luck anyway.
I found out that I have feral bees at my farm when I didn't have any bees there and there was none from the commercial keeps any where around.
I kept hearing the buzzing and found them on the Bahia seed stems collecting the pollen that hangs beyond the seeds. I saw them a couple of weeks ago in the early morning and thought it was strange considering we still had a palmetto flow going. May have been the flow had just stopped.
I have seen them on the seed stems on numerous occasions, usually when I do not have bees at the farm. I have thought about beelining them but there are not enough and there are forests all around making it very difficult to track them.
