Ampeloglypter ater

Ampeloglypter ater is a species of beetle in the family Curculionidae, the true weevils or snout beetles. It is native to North America, where it is widespread and common.

Description

The Ampeloglypter ater is a small beetle, typically measuring between 2 and 3 millimeters in length. It is black in color, with a hard, shiny exoskeleton. Like all members of the Curculionidae family, it has a distinctive snout, or rostrum, which it uses to bore into plant tissues.

Distribution and Habitat

Ampeloglypter ater is found throughout North America, from Canada to Mexico. It is particularly common in the eastern United States. The beetle inhabits a variety of habitats, including forests, meadows, and agricultural fields. It is often found on grapevines, hence its common name, the grapevine weevil.

Behavior and Diet

The Ampeloglypter ater is a herbivorous beetle. It feeds primarily on the leaves and stems of grapevines, although it has been known to eat other plants as well. The beetle is most active during the warmer months of the year, when grapevines are in full leaf.

Life Cycle

The life cycle of the Ampeloglypter ater begins when the female lays her eggs on the underside of grapevine leaves. The eggs hatch into larvae, which bore into the plant to feed. After several weeks, the larvae pupate and emerge as adult beetles.

Impact on Grapevines

While the Ampeloglypter ater is not considered a major pest of grapevines, it can cause damage in large numbers. The feeding activity of the beetles and their larvae can weaken the plant and reduce its productivity.

Conservation Status

The Ampeloglypter ater is not currently considered to be at risk of extinction. However, like all species, it could be affected by habitat loss and other environmental changes.
