JKim Posted June 16, 2019 Report Posted June 16, 2019 I found a female L. elaphus on my recent collection trip. I've collected L. placidus in this same location in past couple times, as well as some dynastine scarabs like Strategus aloeus and Phileurus valgus. Quote
The Mantis Menagerie Posted June 16, 2019 Report Posted June 16, 2019 How can you identify the females of large, US stag beetle species? I have not seen a good guide that explains the differences. Quote

I have not seen a good guide that explains the differences. @The Mantis Menagerie Simply put... 1. Lucanus elaphus is reddish-brown colored, and has triangular clypeus. 2. L. capreolus is reddish-brown colored, and has yellow marks on legs (ventrally). 3. L. placidus is very similar to L. capreolus in general morphology with dark brown to black color. 4. L. mazama has a lot of punctures on all over the body, with dark brown to black color. I will upload pictures of all four species later on. Quote
