I stumbled across this ant counter and made some quick estimates of the amount of workers and brood in some of the images below. The dot placement system is manual, but it only takes a few minutes to complete an image. The dots also reveal how the ants and brood are grouped in each image, something that may otherwise be overlooked. I know some people have already been using this site for quite a while but I thought some other keepers might find this useful in getting accurate population estimates.
