I found this long necked juvenile beetle on a leaf in my garden. That day I was using Canon EOS 70D with Canon EF 100mm f/2.8L Macro IS USM on a 25mm Kenko extension tube. The illumination was by Canon MT-24EX macro twin light flash. This is full frame capture at near 1:1 resolution on this crop frame camera, at f/10 aperture, 1/125th sec shutter speed at ISO 400. later I found out that it is juvenile leaf-rolling weevil belonging to Apoderus sp..

Apoderus beetles are commonly called leaf-rolling weevils. They are not really weevils, but are beetle species belonging to the family Attelabidae and subfamily Attelaninae. Because of the trunk-like elongated head, they are often mistakenly attributed to the weevils.

Apoderus beetle can reach a length of 6–8 millimeters. They have a red shiny bell-shaped pronotum, a shiny black or dark brown head with protruding eyes, a distinct neck and short and rounded elytra. Their straight antennae are inserted near the base of the rostrum. The prothorax is much narrower than the base of the elytra on the abdomen. The scutellum is broad, triangular to trapezoidal and without stripes. Adults can be found between May and September. They feed on leaves being obligatory phytophagous species.

The female cuts slits into leaves, lays her yellowish eggs on them and rolls up these leaves into cigar-shaped cylinders or ‘cradles’ for the developing larvae, that will feed and pupate in these the leaf wraps. The time of oviposition may take several weeks. Several cylinders per day are produced. The adult beetles will emerge in the summer. There are two generations per year.

Apoderus beetle prefers deciduous forests, parks and gardens. These beetles are widespread, but most species dwell in subtropical and tropical zones. Larval development is associated with vegetative and generative parts of plants. Many species make leaf rolls, where larvae are placed; adult insects also feed on plants.
