Spotted Longhorn Beetle
Scientific Name: Rutpela maculata
Category: insect
Brief Description
A striking longhorn beetle featuring a yellowish to olive-green body covered in fine pubescence with distinct black spots on its elytra.
Characteristics
Elongated body shape typical of Cerambycidae, vibrant yellow to olive-yellow wing covers (elytra) with prominent black spots and band-like markings, long segmented antennae, and grayish-black legs.
Habitat
Deciduous and mixed woodlands, forest edges, hedgerows, and gardens rich in old trees or decaying wood.
When to Find It
Most active during late spring and summer, especially on warm, sunny days.
Conservation Status
Least Concern (Common across much of Europe and temperate Asia)
Ecological Role
Adults serve as pollinators visiting various white-flowered plants and umbellifers, while larvae contribute to wood decomposition by feeding inside dead or decaying deciduous wood.
Easily Confused With
Other yellow-and-black longhorn beetles such as Strangalia attenuata or Leptura quadrifasciata, which differ in their specific spot patterns, body proportions, and antennae coloration.
Observation Tips
Look for them basking on sunny broadleaf foliage, flowers of Apiaceae (umbellifers), or resting on old logs and fence posts during midday.
Interesting Facts
The bold yellow and black patterns act as a form of mimicry (aposematism), deterring predators by resembling stinging wasps or bees despite the beetle being completely harmless.
