|Loot||Sapphire glacialis (item)|
|Examine||A sapphire glacialis. It doesn't look as pretentious as its name sounds.|
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.
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 their bare hands. 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 10 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. Catching Butterflies barehanded usually requires both hands free but the Enhanced yaktwee stick can be used here when sheathed. 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. Additionally, they are currently glitched to look white in the wild like snowy knights instead of their normal blue.
