I'm pretty sure it is Aeropostale that uses the butterfly logo...but I'm not so sure any designer uses it. :-)
The butterfly used in the Elektra Records logo is the Morpho butterfly, specifically the Morpho peleides species. This vibrant blue butterfly is known for its striking coloration and is native to Central and South America. The logo reflects the artistic and innovative spirit of the label, which was influential in the music industry.
