Ruby-spotted Swallowtail

The Ruby-spotted Swallowtail (my gallery link) is found from Southern Texas south to Argentina and yes, it reminds me of several Cattlehearts, especially the Pink-spotted, but this is in a different subfamily from Cattlehearts. This is my second observation to not have white spots on the top of the forward wings, which is normal even if in a minority as you can see in my gallery or other online butterfly sites. But, you will see from the only partial side view this one ever gave me that he does have white spots on the underneath side of all wings. 🙂 Another exception in nature and I think that the all black top makes for a handsome butterfly!

A semi-side view shows white spots on the underneath side of both forward and hind wings.

¡Pura Vida!

Milkweed Flowers

Have you noticed how many of my butterfly shots are on the Milkweeds now? 🙂 It is second only to Porterweed attracting the larger butterflies like this and the only flower Monarchs will come to. Tiny butterflies prefer tiny flowers. 🙂 I can’t believe that this is my first year to plant Milkweed! A great butterfly attractor! I recommend it!

Ruby-spotted Swallowtail

Another especially colorful butterfly I got last week at 8th & 3rd was this Ruby-spotted Swallowtail, Papilio anchisiades (linked to my gallery). I’ve seen this one multiple times here in Atenas and also in Jaco at Punta Leona and at Hotel Banana Azul in the South Caribbean. Here’s three different views of the one last week from the sidewalk on 8th Avenue. And yes, he is very similar to some of the “Cattleheart” butterflies here, though all of them have slightly different spots and arrangement of those spots! 🙂 In my best butterfly book I just found about 22 of these large black butterflies with red (pink) & white spots, with 14 of them classified as “Cattleheart” and 8 others as “Swallowtail.” All found in Central America and most unique to here.

Ruby-spotted Swallowtail

Another butterfly today that I’ve seen only one other time, and yes, it looks a lot like some of the Cattlehearts (which are related to Swallowtails), but is one of five black & red & white butterflies labeled “Swallowtails.” You can read a little about the Papilio anchisiades or Ruby-spotted Swallowtail on butterfliesandmoths.org, which are found from Argentina north to South Texas, and for only a few more pix, check out my Ruby-spotted Swallowtail Gallery.
