Red imported fire ant Solenopsis invicta buren workers do not have ovaries

Workers of the red imported fire ant Solenopsis invicta are repeatedly claimed in the literature not to have ovaries. Here, we demonstrate that we cannot find a source publication that proves the statement, and we show how publications are erroneously citing this statement. To remedy this gap, we dissected 87 S. invicta workers over a range of worker sizes, and demonstrate that S. invicta workers do not have reproductive organs. To the best of our knowledge, this is the first time such a demonstration has been published in the scientific literature. We flag that the same issue of a lack of published evidence for the same statement likely exists for many other species and genera, precluding the ability for appropriate referencing of such details.
