M-Jacq
From Make a Good Mega Man Level Contest
Mecopisthes jacquelinae is a species of spider native to Morocco, but you were probably looking for the Sprites INC user with that as her username.
M. jacquelinae, or M-Jacq for short, was a spriter for Make a Good Mega Man Level 2 and Make a Good Mega Man Level 3. She also submitted two levels to MaGMML2; the 15th place entry stage Sector Upsilon 6, and the Tier X level Deep Thoughts. She applied to be a judge for MaGMML3, but was not selected.
