Ladybirds swarm UK due to warm weather, causing disruptions but aiding aphid control.

Ladybirds are swarming in huge numbers across UK beaches and towns due to warm weather, causing disruptions and bites. The surge in population is linked to increased aphid availability, their main food source. Despite the nuisance, ecologists view this phenomenon positively, as ladybirds help control aphid pests. The swarms have invaded public spaces, including a cricket match, prompting comparisons to a similar event in 1976.
