Great capricorn beetle

Great capricorn beetle

Cerambyx cerdo

A species of Capricorn beetles, Also known as Cerambyx longicorn great capricorn beetle

This beetle measures between 41 and 55 mm in body length and is among the largest of the European beetle species. It has an elongated, robust body and, like all members of the longhorn family, it has long antennae. In males, these thread-like antennae are longer than the body, but in females they are only as long as the hard wing cases (the elytra). The legs and body are black, except for the elytra which are reddish-brown towards the tips.

How to Identify Great capricorn beetle?

Life Cycle of Great capricorn beetle
Egg In the egg stage, the great capricorn beetle is encapsulated within a protective outer layer. Size is diminutive, and coloration varies. Larval forms are developed internally until hatching.
Larva As larvae, great capricorn beetle exhibit rapid growth, primarily feeding and increasing in size. Larvae lack wings and have a worm-like appearance with distinct segmentation.
Pupal During the pupal stage, great capricorn beetle undergoes significant transformation within a cocoon or chrysalis. Color and shape are mutable as tissues are reorganized.
Adult Emerging from the pupa, the adult great capricorn beetle'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.

How Can You Attract Great capricorn beetle
Great capricorn beetle can be attracted using pheromone or kairomone bait traps as adults are responsive to chemical cues for finding mates and suitable hosts for their larvae.
Rectangle
Habitat Preferences of Great capricorn beetle Through Different Life Stages
Eggs of great capricorn beetle are typically laid in the crevices of tree bark, specifically in older and weakened hardwood trees. Larvae are found boring into the heartwood of host trees, which can include oak, chestnut, and elm. To encounter larvae, one must search the trunks of these trees, preferably those that show signs of damage or decay. Adult great capricorn beetle can be located on or near the same host trees during mating season, often seen on the bark or foliage. The pupal stage occurs inside the wood, so to find pupae, one would have to carefully inspect and possibly dissect parts of infested trees.
Rectangle
When is the Best Time to Observe Great capricorn beetle
The best time to find adult great capricorn beetle is during their active period which is typically from late spring to late summer, during warm and dry weather conditions when they are most likely to emerge and mate.
Rectangle
What is the Best Weather to Observe Great capricorn beetle
Dry, warm weather is more suitable for finding great capricorn beetle as it encourages flight and feeding activity. Overcast or rainy conditions may reduce the likelihood of encountering this beetle.

How and Where Can You Find Great capricorn beetle at Different Life Stages
Larva Great capricorn beetle larvae bore into wood, so look for them in dead or dying trees, stumps, and large branches, usually hardwood. Search for sawdust-like frass or listen for chewing/noise within infested wood.
Pupal As great capricorn beetle pupate within the wood where they were larvae, finding them requires looking for the same habitat as the larval stage. You may also find them near the exit holes as they are ready to emerge.
Adult Great capricorn beetle adults can be found on or near the host trees they emerged from. Look for them on the bark, at sap flows, or around light sources at night as they are attracted to light.

Forestry Pest

The larva of great capricorn beetle bores into the stems of oak trees for feeding and nesting. Infestations can lead to severe weakening or death of the host, with a large number of pests leading to widespread dieback of trees, potentially affecting wood quality and threatening forest ecosystems. Human industries reliant on these forests may also be impacted.
