What's flying tonight?

This page allows you to see what moths have previously been recorded in Suffolk as adults at a particular time of year. This is intended to give a rough indication of what may be on the wing and not a definitive list of recorded dates (particularly earliest and latest dates). Only records that have been submitted with a precise date are included within the dataset, so records that have been submitted with dates like '12-June-2002 to 16-June-2002' or '2002' are omitted.

The flight data is based on what is flying in a particular week of the year. So what will be shown as flying for a particular time of year is actually the moths that have been recorded flying in the week of the year that the specified date lies in. For example, the 17th August 2004 lies in the 34th week of the year. Confused? - just try it out and hopefully it will become clear.

In the table of results below the 'Total records' column specifies the number of records of that species in the dataset. The 'Weekly Record Total' gives the number of records of that species recorded in the specified week. The 'Percentage of records' column indicates the percentage of records that have been recorded in this week. Species are initially ordered by 'Weekly Record Total' as this gives preference to the more commonly recorded species for that week.

Clicking the and buttons either side of the results table title will show the species lists for the previous and next week respectively.

A wide range of date formats are accepted in the text box below, try things like 20-Mar-2004 or 6/04/04 or 1 07 04
