This is Ceratomia amyntor, the Four Horned or Elm Sphinx. This particular specimen was a county record for Suffolk Co., MA, being found in Boston proper. I always enjoy getting county record Sphingidae, particularly ones in my home-county, or other large urban areas. A project I've been working on this year, and hope to continue into the future is Urban Sphingidae Diversity. I'm mapping Sphingidae diversity and abundance on an urban to rural gradient to see if there's differences in abdunance or diversity. It's an interesting project with some really neat results so far. #Ceratomia #Ceratomiaamyntor #ElmSphinx #FourHornedSphinx #Sphingidae #Lepidoptera #SphinxMoth #HawkMoth #Entomology #Caterpillar #Larva #SphinxLarva #MothLarva #igclub_butterfly #igcb_mothmondays #insects_of_our_world https://www.instagram.com/p/B3adABJg_D1/?igshid=lucu2ce3udlv
