Harlequin ladybird pupa

Harlequin ladybirds use pheromones to communicate with each other, resulting in the formation of large gatherings often seen in the autumn. However, many cues are visual, both long (picking out light-coloured structures that are distinct from their surroundings) and short (picking out pre-existing aggregations to join) ranges, while nonvolatile long-chain hydrocarbons laid down by previous aggregations also play a significant role in site selection. Both are more important than volatile pheromones.
