What kind of bug is this? It looks like it is half dragonfly, half butterfly with blue and black markings.
Dear Lake Lover,
Many Dragonflies have beautiful coloration and markings, including this Eight Spotted Skimmer, Libellula forensis. BugGuide notes this bit of trivia: “Years ago many children refered to this as the ‘Six-spot’, and counted the basal spots as two crossing the thorax, instead of four separate spots. The same went for the then ‘Ten-spot’, which most recent books have switched to calling the ‘Twelve-spotted Skimmer’. The “Six-spot” name doesn’t seem to appear in any books, but was likely rationalized from comparison with the ‘Ten-spot’ that was to be found in many books. Back then, Libellula forensis didn’t seem to have an established published common name yet.”
