About

Stenocorus meridianus is a common species of longhorn beetle found in the UK. These beetles are mainly herbivorous and feed on leaves, bark, and occasionally flowers. They have a dark reddy brown or black colouration although this can be variable. They usually emerge during summer, flying around oak, ash, and willow trees, looking for suitable feeding sites or potential mates. It’s worth noting that despite being relatively common in the UK, they are considered an important indicator species for monitoring the health and diversity of our woodland habitats due to their specific habitat requirements.
