The Mosquito is a small and light bearing concave model. Made to break the $10 price point in the Duncan line, while still providing high performance.
Both body and sides are opaque white, but the caps are held on with screws. Take a look at the response view to see the screws. This differs from the earlier Mosquitos. While it was shipped with friction stickers, under the stickers was a starburst response. So this one could be played with friction sticker response, starburst, or a combination.
Pictured here is the limited release version of the Mosquito from the 2005 Worlds.
