Players can find ruby harvests at the Piscatoris Hunter area just south of the Piscatoris Fishing Colony (fairy ring code ). They must wield a butterfly net and have at least one butterfly jar in their inventory to catch them (To wield the net in your hand, right-click on the action bar's minimise icon and toggle the 'Sheathe/Unsheathe Weapon' option. One jar is needed for each butterfly you wish to keep). All of these items are available for purchase in Hunter stores, an example being the shop in Yanille. Jarred ruby harvests can be used on another player to increase their Attack level.
