ABSTRACT. Large collections of crayfish made throughout Indiana during the past several years have increased our knowledge of various aspects of the biology of Indiana's crayfish fauna, including Orconectes (F.) indianensis, a species that had conservation status. New information on distribution, taxonomy, life history, or habitat is provided for Orconectes (Faxonius) indianensis, Orconectes (Trisellescens) immunis, Orconectes (Crockerinus) propinquus, Orconectes (Procericambarus) rusticus, Cambarus (Tubericambarus) sp. "A," Cambarus (Erebicambarus) tenebrosus, Cambarus (Erebicambarus) laevis, Procambarus (Ortmannicus) acutus and P. (Scapulicambarus) clarkii. Reproductive biology, fecundity, egg diameter size, and instar lengths are provided for Orconectes (F.) indianensis, Orconectes (T.) immunis, Orconectes (C.) propinquus, Cambarus (T.) sp. "A," and Procambarus (S.) clarkii, including chronology of appearance on the female abdomen. The largest ova diameters belong to Cambarus (T.) sp. "A" and Procambarus (S.) clarkii with diameters between 2.1-2.5 mm, while Orconectes (T.) immunis had the smallest ova ranging between 1.4-2.0 mm. Keywords: Distribution, taxonomy, life history, habitat
