not sure mikey, but these appear to be some type of 'hover fly', these are honey bee and wasp look a likes. drone fly, flower fly, many common names.
look up 'drone fly, Eristalis tenax
' and also 'flower fly wasp (Helophilus pendulus )
', or 'Syrphid Flies
'...... these are of the 'syrphid or Syrphidae
(Taxonomic Classification). (for north caroliina) images and articles.
the drone fly can look like a honey bee and perhaps an old honey bee, as perry mentioned. what caught my eye was the first picture, the distinct coloring, hairless, and wing structure.
