Really just a guess, but I believe a lot of butterflies are brightly colored to indicate that they're poisonous/taste bad. The spider might just be annoyed by the butterflies and want them gone, instead of actually wanting to hunt them. It might also be a species that feeds exclusively on another sort of insect, like flies, so it doesn't have the instincts to try and hunt the butterflies. Very neat interactions regardless!
Butterfly- Whoa! Look at those spider veins.
ABBA sings for the spider -
The Winner Takes It All
Aw yeah, Mister Crabs!
0:59 finally taps it with his stalks and realizes something aint right
How do u not see a fat spider sitting right infront of u😭
That's cool. Why doesn't the spider grab them though? It is poised like it wants to but only halfheartedly tries near the end of the video.
Spiders are only powerful if you show them fear
