Life Cycle of Rhubarb curculio
Egg The egg stage is marked by a small size and distinct coloration aimed for camouflage. The eggs of rhubarb curculio are typically oval, have a protective shell, and are laid in clusters or singly on host plants.
Larva During the larval stage, rhubarb curculio exhibits rapid growth. The larvae are worm-like, lack wings, have chewing mouthparts for feeding voraciously on plant materials, and undergo several molts while increasing in size.
Pupal In the pupal stage, rhubarb curculio is encased in a protective cocoon and undergoes significant transformation. The creature is immobile, and its tissues are reorganized into the adult form, with changes in shape and function.
Adult Emerging from the pupa, the adult rhubarb curculio's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Habitat Preferences of Rhubarb curculio Through Different Life Stages
The eggs of rhubarb curculio are typically deposited on host plants, particularly on stems or leaves of thistles. Larvae can be found within the stem tissue where they feed and develop, often requiring the dissection of plant stems to be observed. Searching for larvae would thus involve examining host plants, particularly looking for signs of feeding or entry points on stems. Pupae will also be within the plant tissue or in the soil nearby. Adults emerge from their pupal chambers and are commonly sighted on or around host plants, feeding on foliage. To find adults, one would inspect these plants, especially on warmer days when they are most active.

Agricultural Pests

Adult rhubarb curculio beetles are known to feed on asparagus, causing mild to severe damage. They chew plant tissues, principally stems and leaves, which can suppress plant growth and lead to yield reductions. In severe cases, widespread damage might significantly impact asparagus production. Consequently, this may affect the availability of this crop for consumers and lead to economic losses for farmers.
