So I think I got the top row, but does anyone know the bottom row? Thanks!
Top: dynastes Hercules, dynastes neptunus, dorcus titanus/antaeus, prosopocoilus giraffa, papuakin yellow stag, Trypoxylus dichotomus
I live in Southern California, found these grubs in damp soil at the base of a tree. 2.5cm length. Thought maybe Cotinis mutabilis, but it doesn’t crawl on its back. Has single anal slit, can’t tell a particular raster pattern. Could it be a Lucanid? Thanks!
