Horsefly vs. Butterfly: The Rematch!

Tyler Scagliarini, horsefly, butterfly, Eyewire, citizen science, Lewis Carroll

Now and then, HQ likes bringing you a blast from the past: a chance to revisit an old VS and see which team will win on a second round! This year, we can’t resist a favorite inspired by Through the Looking Glass… it’s “horseflies” and “butterflies.”

You can read the original post here, complete with the Lewis Carroll quote; but either way, if you missed the original event, now is your chance to re-decide which mysterious creature should reign supreme. The competition starts at 11:00 AM EDT on 5/10 and goes for 48 hours!
