The Male Phasmid is one of the 24 Golden Bugs found in The Legend of Zelda: Twilight Princess. Like most male insects, it is green in color. Giving this bug to Agitha will reward Link with a Rupee prize.
The Male Phasmid is located around the southern end of the Bridge of Eldin. As Link enters the bridge from Hyrule Field, he can find this Golden Bug situated on the left (Wii) wall. He can use his Boomerang to retrieve it.
