Reported as an adult

Usually reported as an adult late May to late August, middle week Jun 28 – Jul 4.

From 363 records that are marked as adults. Not every photo is marked with a life stage, so this shows when people reported it as an adult, not when adults are about.

Reported as a larva

No records here are marked as larvae yet, so there is no larva season to show. One needs at least 20 records from 5 different years.

What these results show

These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.
