While previously considering Lana Lang in a collection piece on the Superman Family, she (or rather they) deserve more indepth analsysis.
On Earth-One, Lana was a childhood friend of Clark Kent and a love interest of his alter ego Superboy. Sure she was a pest at times, and a snoop...something the Kryptonian crusader would gravitate towards again and again with his women. Still, she was his first love and a courageous ally in his battles for justice.
During one occasion, when Lana saved an alien stranded on Earth, the being gave her a bio-genetic ring that gave her temporary powers. This allowed her to transform her body into any insect like form and gain its abilities.
Eventually she took a cue from her boyfriend and adopted the identity of Insect Queen having several adventures in Smallville. She was later made an honorary member of the 30th century Legion of Super-Heroes, of which Superboy was both their inspiration and founder.
Over on Earth-Two, decades prior, that world's Lana Lang left with her parents from Smallville while still very young moving to Metropolis. This was due to the fact that the small town never grew, since there was never a Superboy there to draw publicity to it. Hence, when she approached Editor-in-Chief of the Daily Star as an adult, she was relatively unfamiliar to Clark Kent.
Shortly after joining the newspaper's staff as a television critic, Lana's father Professor Lang found an ancient amulet during an archeological dig in Egypt. Sending the broach to his daughter, it was later learned that it originated from a Pharoah empowered to protect his people from impending locusts plaguing the land. With the fluttering on wings, the amulet would activate the wearer to the need to protect civilization from impending threats. However, it was the sound of Superman's cape that spawned the creation of Insect Queen. First a foe then eventually an ally, she would herself encounter insect aliens though not benevolent as the one her counterpart met, instead desiring to conquer Earth. She defeated them using her powers to both enlarge and control insects.
