 Queenright colonies of "A. andreniformis" have also been observed to adopt queenless workers of "A. florea" as well, but their policing on non-natal larva has not yet been studied.Unlike cavity-dwelling honey bees whose queen has a distinct chemical signal from that of the worker bees, "A. andreniformis" queens have similar chemical signals as their workers.Chemical signals secreted from the mandibular gland in "A. andreniformis" are not caste-determining like it is in other honey bees.
