This is Bashful Bug from the animated 'Glo Friends' series (mid 1980's).
The 'Glo Friends' was an 11-minute show that ran along with 'My Little Pony 'n Friends' (MLP'n F). MLP'n F would rotate its secondary segments, os in addition to 'Glo Friends', 'Potato Head Kids' and Moondreamers' were also part of the show (the ponies have many friends, it seems).
So... what are Glo Friends? Are they all lightening bugs or fireflies?
No, the insect species were varied, albeit several characters of distinct species look very similar to me (the Glo Friends are just slightly more distinguishable from each other than The Berenstain Bears). :p
I chose Bashful Bug because Glo Worm was annoying to draw (I dunno why, but I couldn't seem to curve his segments to my satisfaction---after a few attempts, I gave up). :p The Glo Friends, in general, seem to have a freeform hand to them; intuitive for their animators (who draw the darn characters hundreds of times a week), but this was my first attempt ...so I don't feel (too) bad. ^^
Pencil...
The featured pencil is a WWII-era 'Firefly' by Wallace Pencil Co.
Mine's not been sharpened, so ...I drew Bashful Bug via my Wallace 'Zepyhr'. Wallace makes good pencils in general (the 'Swift' being an exception), so I'm sure the Firefly is good. :3 My Bashful Bug card was delineated via a Rapis Extra. :3
