Temporal Distribution Chart
Adults: (between 1995 - 2026)
(click legend below to show/hide datasets)
This chart summarises all available historical occurrence records collated by ISO week of the year. It reflects recorder effort and sampling distribution as well as true biological activity, and should be interpreted as an indicative pattern of seasonal occurrence rather than a statistically controlled abundance or phenology model.
Changes in First and Last Recorded Activity Dates Over Time
Activity Data Range:
1995 –
2026
Earliest Appearance:
1st June (in 2002)
Latest Appearance:
21st July (in 2012)
This chart presents a time-series summary of recorded observations. It is based on available records at the time of analysis and will evolve as further data are added. The rolling mean provides a smoothed representation of variation in recorded activity over time. Annual record totals are shown for context; years with fewer records may provide a less complete representation of activity than years with higher recording intensity. Interpretation should consider that apparent trends may reflect both biological change and variation in recording effort.
