  1. Hey Norman,

    Great article on the Eastern Tiger Swallowtail Butterfly! I thought a lot of the facts listed were unique and interesting like how it can lay 250 eggs during its short lifespan and the whole bird droppings thing is crazy! Just shows how smart mother nature is that it could think to disguise butterfly eggs as bird poop.

    • Thank you so much for your kind words, these are some amazing facts about the eastern tiger swallowtail butterfly. I am so happy that I could help.

  2. Hi Norman

    You certainly know alot about the Eastern Tiger  Swallowtail Butterfly. I must admit that I do not have alot of knowledge about butterflys as a whole. However, I do know that they are prevalent during the warmer months and are found around flowers and fruit. They also seem to add to the ambience of a place and everyone loves them. 

    I recently moved into a new home and have yet to get started with my new garden. It would be lovely if my new garden turned out to be a butterfly sanctuary.

    Thank you for the article.

    • Thank you so much, butterflies are so beautiful and will brighten up a garden with their colors along with adding so much activity. Once you plant in your garden what beautifies likes as far as a food source (plants that attract them) they will come. Hope this helps.

  3. Hey great article! I love nature and butterflies are beautiful. They’re fascinating how they go from being a caterpillar into a beautiful delicate creature just by being inside a cacoon.
