Orange Swift

Fascinating facts about the Orange Swift

• The orange swift does not possess a proboscis, so it never visits flowers to drink nectar. Even when night-time lights draw it out, it cannot feed on blossoms because it lacks the mouthpart needed for sipping. Its activity is limited to flying from June to September, when it is attracted to artificial light. Consequently, observers never see it feeding at flowers.
• Female orange swifts release their eggs while hovering directly above the host plant, scattering the globular, shiny black eggs into the surrounding area. This broadcast method ensures the eggs land close to suitable food sources for the emerging larvae. The hovering behaviour is described as the female moving over the food plant as she deposits the eggs. The eggs are therefore dispersed without being laid on a surface.
• After hatching, the larvae immediately seek out a root, bore into it and grow to a length of 25 to 30 mm when fully fed. They remain underground for two full years, feeding from September through July on the roots of a variety of plants. Their diet includes bracken, dandelion, docks, hop and viper's bugloss, allowing them to exploit several common herbaceous species. This prolonged subterranean feeding period supports their development before pupation.
• Male orange swifts are instantly recognisable by their bright orange forewings crossed by two white bars that meet to create a clear V-shaped mark. This vivid pattern sits on a wingspan that ranges from 32 to 48 mm, placing the male within the smaller end of the species size spectrum. By contrast, females are generally larger and their wing colouration is duller, making the male's display even more striking in flight.
• When the larva is ready to transform, it builds a silken cocoon just beneath the soil surface and the pupa develops inside an elongated body equipped with hooked bristles on its abdominal segments. Shortly before the adult moth appears, the pupa breaks free of the cocoon, allowing the imago to rise and take its first flight.
