Singapore’s Leaf Rolling Weevils

7 September 2012
Leaf Rolling Weevils are sometimes known as Giraffe Weevils due to their longer necks. The necks in the males of certain species are extraordinarily long, but we have not seen those in Singapore yet.

Here’s a video showing how this weevil cuts a leaf and rolls it up into what looks like a spring roll. This rolled leaf serves to protect their newly laid eggs. Some species would cut the rolled leaf and let it drop to the floor, while I’ve seen some left hanging on the branches. When the young are hatched, the larvae will feed on the leaf from inside until they are ready to face the world.
