What an interesting idea! Come to think of it, I venture to suggest that Apis dorsata may forage in teams. In Indonesia when these bees are foraging on Decaspermum treelets, they appear en masse over a short span of time (minutes) and when the foraging stops, it does so equally abruptly. Foraging takes place over a couple of hours every second day, when the flowers open. The flowers remain open all day, but it is only in the morning from ca. 8:00 a.m. to 10:30 a.m. that the dorsata bees are present. Andrew Lack (Oxford Polytechnic) and I describe this activity in our paper in Biol. Journal of the Linnean Society 25:319 - 330 (1985). Reprints are still available to interested Bee-Liners who want to send their postal addresses. Now, whether the almost synchronous arrival and departure of the bees represents team foraging, I don't know. It would seem difficult to completely divorce "team-foraging" from recruitment. There may be another "team" approach to foraging by some bees. I suspect that some Trigona guard floral patches for nest mates who are foraging. I can't remember reading anything about this sort of team approach of guards and foragers, but perhaps others have. Does Roubik make note of anything like this, I wonder?
