In response to their strikingly similar coloration, we tested for a mimetic relationship between Notophthalmus viridescens louisianensis (Central Newt) and Macrobdella diplotertia (Ozark Highlands leech). Early observations took place in a south-central Missouri woodland pond. Later, feeding experiments involving ducks, geese, and native fishes were conducted. Our results support a mimetic relationship between these 2 species that is not a simple classification. More in-depth study may be needed to elucidate the true nature of this relationship.
