It is an insect called a butterfly. It has 2 wings with large tops on the wings and small parts of wings at the bottom. The wings are connected onto the body in the center.
This is a Butterfly icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
