2392. Water Sprite

Dazzling in color and about the size of large insect, Sprites have glistening membranous wings. In fact, they are often confused with exotic Insects or flowers at first glance.
Considered by many to be the most common type of Faerie, they live in deep woods and make their homes high in the branches of trees. They particularly love to live in forests inhabited by Treefolk other Fey. If Sprites are spotted, you can be sure you are in an area with a high concentration of Faerie activity.
Sprites travel in swarms and can bite if provoked. At night their bodies give off a faint glow that can have them mistaken for Fireflies, which, along with other flying Insects and small birds, they are fond of riding.
Petals and blooms missing from healthy plants may be due to Sprites plucking them for clothing. Sprites can also cause Plants to bloom in the middle of winter and are the nurturers of the strange fruits that Faeries delight in.
In forests with Sprites, you may find the hollowed-out acorns they use as cups, dandelion-tuft mattresses and hats made from folded leaves. (Compare to Will-o’-the-Wisps) Sprites are a constant reminder of all that is magical.

2385. Pink Flower Sprite

 

Sprites are magnificent creatures varing in color, form and shape. They may cause flowers to bloom yet can deliver surprisingly fierce bites when threatened. They are extremely shy when it comes to strangers, but can easily become attached to those who are kind or helpful to them. They are usually mistaken for large exotic insects or flowers. In the night they are sometimes even mistaken for fireflies due to the fact that they give off a faint glow. They are also known for randomly giving juicy red berries to their friends/owners, but if eaten taste amazing, like nothing you have ever tasted before, and that would be a good thing, except that human food will taste bland, plain as "sawdust" and whoever eats one will have to go on eating those berries for the rest of their lives since they cannot bare to eat human food.

When thinking about keeping a sprite as a pet/companion, you need to consider the following:
How will you acquire your sprite? Where will you house it? How will you be sure it gets the proper exercise and correct nutrition? The book: The Spiderwick Chronicles: Care and Feeding of Sprites has good facts and ideas. Here are some easy tips to remember:

1. If keeping a Sprite inside your house, it will be most happy in a flower pot or some kind of indoor plant, placed somewhere with lots of sunshine (like a window) with a view of the outside.
2. DO NOT capture a Sprite by caging it. You must first earn it's trust by feeding it or becoming correctly acquainted with it and then you may lure it to wherever you want. If you cage it or scare it, in defense it may bite or nip.
3. One thing most all Faerie folk like to drink is lukewarm milk, it is sweet and tasty. This is one way you can lure a Sprite.
4. Make sure your able to see them before getting one if not you might be looking or even talking to an empty cage.
