Financially secure Ehrman was able during his later life to devote himself to natural history including ornithology. He made extensive collections of the Lepidoptera and Coleoptera of western Pennsylvania then extended his
collections worldwide. He specialised in Papilionidae, the genus Catocala, and the butterflies and moths of
Liberia, and the beetle genus Cychrus and its allies.
His collection of American und exotic Rhopalocera and Coleoptera was bequeathed to the Carnegie Museum of Natural History. The species described by him are listed by Holland (1927) [1]
