Kiertokiitäjä moths attract attention in Finland as sightings reach record numbers this autumn

The Kiertokiitäjä (Agrius convolvuli), known for its frequent visits to white tobacco plants, is currently drawing attention from butterfly enthusiasts who are cultivating this nectar-rich plant to attract the moth. When visiting flowers, Kiertokiitäjä does not land but extends its long proboscis—over ten centimeters—directly into the blossoms. This species can be observed at dusk and again in the early morning. During the day, Kiertokiitäjä may be found resting on walls.

This autumn, butterfly watchers have noted the simultaneous presence of multiple Kiertokiitäjä individuals fluttering around white tobacco plants. In recent years, sightings of these moths have increased significantly, with this autumn witnessing record numbers. The Kiertokiitäjä is a regular inhabitant of Africa, the Middle East, and the southernmost parts of Europe, migrating north during summer months and reaching as far as Finland.

Additionally, other migratory moths have been reported due to warm air currents this autumn. Among them is the Hukkavaellusyökkönen (Helicoverpa armigera), observed in greater numbers than ever before across Finland. Millions are believed to have arrived with the warm winds, even reaching northern regions of the country. There have also been notable sightings of the much smaller Kulku tähtikoisa (Euchromius ocellea). The prolonged warm southerly and southeasterly air currents moving toward Finland may be bringing moth species that have not been documented in the area before.
