Description

This is the larvae of the Nut Weevil. There are several beetles of the Curculionidae family that predates various nuts. The Nut weevil (Curculio nucum) can be very serious pests of native and non-native nut trees like Hazelnut. These damaging insects begin to attack the kernels in the developing nuts while the nuts are still on the tree. However the damage is often not noticed until the nuts are harvested and opened. The now empty nut has a hole where the young weevil emerged. The nut weevil, like all weevils, is a beetle with a long snout or proboscis which is longer in the female. Occasionally, these weevil grubs are found in homes or other places nuts are stored. The weevil pupates into adults from April to July and are often seen getting nectar from hawthorn blossom. The female uses her long snout to drill into a young hazel nut, then lays an egg in the hole. The emerging larva feeds on the kernel until autumn, when the nut falls to the ground. The larva gnaws its way out of the nut and digs into the soil to pupate over winter. Picture from Wikimedia Commons.

Control

Weevils usually move only a short distance after emerging and often attack nuts on the same trees year after year, so long as there is a crop of nuts. Sanitation is important, always collect and destroy fallen nuts before the larvae have a chance to escape and enter the soil. Watering the soil with an insecticide at the right moment should control this pest. Spraying just after petal fall may also help. Certain nematodes may attack the weevils in the soil.
