You can easily differentiate males and females: The male has a distinctly longer neck, which makes almost the half of its total length. The whole life of these small animals is bound to only two small growing trees, Dichaetanthera arborea and cordifolia. Both belong to the Melastomes, look more bush like and wear finely haired, green leaves. During their whole lifecycle of estimated one year, the giraffe necked weevils never go to far away from their trees. It is assumed they feed on leaf sap, but noone did researches on this topic yet.
