Amaze your friends! Tell them the sex of butterflies like this Black Swallowtail!

Insect black swallowtail male

This is a male Black Swallowtail butterfly. Obvious differences between black swallowtail male and female are found in the big yellow “V” on their wings. The male’s “V” pattern looks like it is composed of a long row of crooked yellow teeth. The female’s “V” is made up of a line of small yellow dots. The female also has more blue on hind wings, similar to the female tiger swallowtail. Swallowtails are easy to observe because they spend a lot of time drinking flower nectar. It doesn’t even take much patience, just some flowers.

The books and a booklet series based on each different yarn craft topic covered in "The Yarn Animal Book" (pompoms and other really easy yarn crafts, knitting, crocheting, rya, needlepoint and embroidery), are available on Amazon and Kindle.
