Black and yellow longhorn beetle is a part of the flower longhorn (Cerambycidae) family and lepturine beetle (Lepturinae) subfamily. They are found in almost all of Europe, attaining their name due to the black and yellow spotted appearance.
Size: 13 – 20 mm (0.51 – 0.79 inches)
Color: They have a dark brown head and pronotum and yellowish elytra marked with black stripes and dots all over. Their front legs are yellow, tipped in black, while the hind legs mostly remain black.
Other Characteristic Features: One of their most striking features is their long antennae, which is quite characteristic of the majority of the longhorn beetle species.
The larva with a pale appearance mostly dwells in the rotten woods.
Like most other longhorn beetle pupae, the pupa for this species remains in the sapwood’s pupal chambers until it matures as an adult.
The eggs, small and round, are mostly laid in the sapwood of the rotten stumps.
| Other Names | Spotted longhorn |
| Lifespan | Approximately 2 – 4 weeks |
| Distribution | Major parts of Europe including France, Greece, Germany, Denmark, Czech Republic, Finland, Poland, United Kingdom, Switzerland |
| Habitat | Larvae: Mostly rotten woods of deciduous trees, which is their primary food source Adults: Near Apiaceae species and hawthorn flowers |
| Common Predators | Birds |
| Seasons active from | May-August |
| Host Plants | Larvae: Norway spruce, European beech, common hazel, willows Adults: Hawthorn and Apiaceae species |
| Diet of larvae and adults | Larvae: Dying or rotten wood of the trees they live in Adults: Nectar and pollen of their host plants |
The larva seems to dig a lot and make holes in the wood, causing damage to the trees or even untreated lumbers.
