Spotted Sulphur

Fascinating facts about the Spotted Sulphur

• The spotted sulphur was once a regular resident of Great Britain but has not been recorded at any known breeding site since 25 June 1960, leading to the assumption that it is now extinct there. Its historic range covered most of the Palearctic, extending from Europe and North Africa through the Middle East into Russia, northern China and Japan.
• Spotted sulphurs produce two overlapping generations each year, although the second brood often fails to develop in cooler summers. Adults are on the wing from May to August depending on locality, and a later flight period runs from August to early September when conditions allow. This bivoltine pattern means that in favourable warm years both generations emerge, while in cooler years only the first generation is typically observed.
• When active, the adult spotted sulphur makes short, jerky flights close to the sun-lit ground, a behaviour that makes it difficult to observe. It prefers dry, sandy habitats such as meadows and sunny slopes where bindweed grows, matching its habit of staying low to the surface. These low, rapid flights in open, warm areas help the moth stay within its preferred microclimate while searching for mates and oviposition sites.
• The spotted sulphur seeks out dry, warm meadows and sunny slopes where the soil is sandy, because these conditions support the growth of its favourite plant, bindweed. It is especially common on sites where bindweed is abundant, linking its distribution tightly to that herb. The caterpillars rely on field bindweed for nourishment, feeding on Convolvulus arvensis as they develop.
• That publication marked the formal introduction of Emmelia trabealis to the scientific community. Since then the name has been retained, although the genus placement has occasionally shifted between Emmelia and Acontia. The original authority remains a cornerstone for all subsequent taxonomic references to the species.
