To clarify: Eastern Tiger swallowtails - the yellow ones!

The front of a GST cat is orange-ish while the TST is brownish. Since you have 5, I'd go GST. I've never had a TST leave me more than two eggs.

I'm thinking Giants. Pics are below, and I also found one on my rue, which TSTs don't use to my knowledge.

They are so odd looking, it makes them adorable!

"nothing to see here, I am a bird poop, not a tasty caterpillar"

Yep, very odd. Adorable... they kinda gross me out. (shhhh... don't tell them!)

theparsley: lol

Just when I thought they couldn't be uglier - lol. Thanks for posting the pic!

I was just outside hunting for more eggs on my wafer ash, and I saw a dark form Tiger! I stayed very still, but she still flew off to my neighbor's tulip tree :(

On the upside, I found 1 tiny BST cat and 4 BST eggs on my rue! The eggs were laid today, because I was out there last night and there were none. Yay!!

Tiger eggs are green so tougher to notice. I missed the one I had this year until it was 3rd instar.

Happy Update: I now have 18 Giant Swallowtails to raise!! From my original 5, one didn't hatch, 3 have made their chrysalis, and one is about to.

I only recall having Giants once, in 2011 I think, and only 4 or 5. Yesterday I found 13 eggs, and this morning one more! Momma is laying on my wafer ash, and the orange eggs on the dark green leaves are easy to spot if you're looking for them.

I am giving my best friend one of the chrysalises - I have not told her what it's going to look like, and she doesn't use the internet much, (weirdo!), so I doubt if she'll look it up. She's only gotten BSTs and Monarchs in the past. She's going to faint! :)

Make that 19! Found another one this afternoon - I can't believe how many I have!! I bring them inside to raise - I love watching them grow and of course eclose!
