From Fritz Müller 12 September 1875
Summary
Has read CD’s book on Drosera [Insectivorous plants] and found that it presents new material and is very interesting.
Has discovered that the parasites he thought he had found in Melipona nests are in fact true females. It is remarkable that they differ so greatly from the sterile females and males of their species.
