Flight periods

Light gray color shows the general flight interval of the species from the relevant area.
Dark gray color when the species is most numerous.
A black spike means a peak moment.

Probably with all species extralimital observations exist, and more will come with the ongoing global warming. I'll make corrections as seem fit. As of 2026 flight periods are only made for European species.

Scandinavia (Norway, Finland, Sweden and Denmark): Based on Billqvist 2023, but updated to current state (2025), based on the relevant citizen science databases.
Europe meaning the general pattern for the entire continent, also separated into a northern and southern region where it makes sense. Based on Smallshire and Swash (2020).
