Reported as an adult

Usually reported as an adult mid-May to early September, middle week Jul 26 – Aug 1.

From 485 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 caterpillar

Usually reported as a caterpillar late June to mid-September, middle week Aug 16–22.

From 42 records that are marked as caterpillars. Not every photo is marked with a life stage, so this shows when people reported it as a caterpillar, not when caterpillars are about.

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.
