Swallowtail butterflies

Asked August 13, 2019, 1:18 PM EDT

I’ve noticed an increase in butterflies this year, particularly swallowtails. Any insight?

Yes, this certainly has been the year of the swallowtails and apparently, this is happening in other areas of the east coast as well. However, there is no official reason for this. In general, insect populations ebb and flow each year due to weather conditions, fewer predators or parasitoids that prey on them and other reasons........


Interesting, thank you so much! I will continue to enjoy the butterflies ❤️
