The Sapphire glacialis is a butterfly that players can capture with the Hunter skill at level 25 or above, granting 34 Hunter experience. A good place to catch them is on the second level of the Rellekka Hunter area, near the stairs. There are two spawns close to each other with small wander distances. Catching them here with an enhanced yaktwee stick, kyatt clothes and an arctic bear summoned will yield around 110k hunter and 17k agility experience per hour at level 85.
Players can find sapphire glacialis at the Rellekka Hunter area area, north of Rellekka. When used on a player, it boost the target's Defence. As usual, it requires a butterfly net and butterfly jar to catch, both of which can be bought at any Hunter store.
At level 85 Hunter and 80 Agility, the player can catch a sapphire glacialis with his/her bare hands. Following an update, the player's hands no longer have to be empty, as a result, it is recommended to wield the Enhanced Yaktwee Stick to increase experience gain. The player will follow it until it is caught. Catching a sapphire glacialis with this method gives the player 400 Hunter and 70 Agility experience. Following an update on 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. Butterflies respawn very quickly; to minimise the amount of time running around trying to find them, camp a spot that spawns a butterfly with a small wander radius.
After catching a sapphire glacialis, players can use it on another player to increase the other player's Defence level.
Sapphire glacialis butterflies are often mistaken for the more popular Snowy knights because they look similar and are found in the same area and can sometimes be difficult to see due to the colour of the ground.
