|Examine||It's a ruby harvest butterfly.|
Players can find ruby harvests at the Piscatoris Hunter area just south of the Piscatoris Fishing Colony (fairy ring code A•K•Q). 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.
With level 80 Hunter and 75 Agility, the player can catch ruby harvests with their bare hands. It may take several attempts to catch one, and the player will follow the butterfly with a jumping animation until it is caught. Doing this gives 300 Hunter experience and 50 Agility experience. Since barehanded butterfly catching requires both hands free, the Enhanced yaktwee stick cannot be used here. Following an update on the 13 September 2013 catching a butterfly bare-handed gives a chance of obtaining a Crystal triskelion fragment. After the butterfly has been caught the player will release it, meaning that the butterfly cannot be kept.
A good technique to capture them is to click one to begin hunting, then right clicking another. This way, you already have your next target without having to search, allowing you to hunt faster. Also, since butterflies respawn very quickly, another method is to camp a spot that spawns a butterfly with a small wander radius. This minimises the time spent running around.
A common strategy is to set up some bird snares while hunting ruby harvests, increasing the maximum exp gain a player may get.
Catching with a net and jars is currently a great, fast but uncommon way to make money. However, the popularity of this method has grown due to the price rise caused by this being made a secondary ingredient for the summoning familiar, Forge regent.
After catching a ruby harvest, players can use it on another player to increase the other player's Attack level.
Pay-to-Play players can catch ruby harvest butterflies and sell the Ruby harvest (item) and make around 30k per full inventory.
