  1. Yes, the only way to distinguish between Pyrgus communis and P. albescens is to collect a male and look at the valves under magnification. The word "dissect" is a little too strong in this context. You can usually make the valves visible just by carefully brushing away the scales at the tip of the abdomen. And you don't need much magnification to see the difference in the valves. A child's toy microscope would probably be adequate, although a pretty decent "student" microscope can be had for about $200. John Burns spelled out the diagnostic differences and provided plenty of examples in his 2000 paper, "Pyrgus communis and Pyrgus albescens (Hesperiidae: Pyrginae) are separate transcontinental species with variable but diagnostic valves." It's available online: http://images.peabody.yale.edu/lepsoc/jls/2000s/2000/2000-54(2)52-Burns.pdf
  2. CC is correct about the choices for Checkered-Skippers in Mississippi. The Tropical Checkered-Skipper is identifiable in photos -- and this is not one -- leaving Common and White as the remaining options. If you didn't know the location, you would need to collect and dissect a male in order to confidently identify the species. However, this far south in Mississippi you can be very sure this is a White Checkered-Skipper just from the location. Source: have collected and dissected a lot of Pyrgus in Mississippi. J
  3. Yes, Long-tailed Skipper (Urbanus proteus).
  4. Butterfly ID/confirmation

    I'm pretty sure that's a male Sachem.
  5. Not a clearwing, rather a crambid. I think it's Diaphania hyalinata, the Melonworm Moth, but it might be something else in Diaphania. There are several similar-looking species.
  6. Not an expert, but I'll suggest Hummingbird Clearwing, Hemaris thysbe.
  7. ID Please

    Moth in the Desmia genus. Don't think it's possible to get to species level without a shot of the underside.
  8. Algonquin Park (Ontario) moth

    Or Brown Angle Shades?
  9. Southwestern Ontario Moth?

    Virginia Ctenucha moth (Ctenucha virginica)
  10. 1. Northern Pearly-eye 2. & 3. Baltimore Checkerspot 4. & 5. Polyphemus moth 6. Little Wood-Satyr
  11. Not sure butterfly

    Nice shot of a Red-banded Hairstreak.
  12. Arizona Butterflies

    It's not my region, but I'll give it a shot anyway. Grain of salt. 1. Texan Crescent 2. Pipevine Swallowtail 3. Southwestern Orangetip.
  13. Costa Rica Butterfly ID

    Think that's one of the Preponas. Maybe Archaeoprepona camilla. I don't have any personal experience with these.
  14. Help Identifying some butterflies

    That second butterfly is not a native Ohio species; it looks like one of the tropical Heliconius species. Was this photographed at a butterfly house or indoor exhibit?
