Anise Swallowtail
Lens: DA35 Camera: K5 
Posted By: Timtast1c, 10-16-2011, 06:50 PM

I haven't posted in a while but I've been working on a project lately. It's difficult to describe the process in just a few photos so there are a bunch!

I found a group of 5 caterpillars in july on the same plant that I found caterpillars on last year. The adults emerged and laid eggs....about 100.

Come a month later and all 100 butterflies hatched and laid eggs again.

Here's a little insight on the project.

Caterpillars are in their last growth stage (5th instar) and are eating voraciously to pack on enough fat before becoming chyrsalis. They ate all of the leaves you see.....X5.


Caterpillar Bokeh.


An unusual black and teal morph showed up in this batch

Some on the top left have already emerged. the rest are still developing. The skin becomes clear about 12 hours before emergence

Turn around for a minute and there are more!

Emerged adults move to the top of the enclosure and hang upside down to inflate their wings to full size. They are ready to fly in about an hour

The group! A soft hamper doubles as an excellent transfer container.

While the weather was bad outside I kept them inside in a tent.

Two Males

Males of this species exhibit a behavior known as hilltopping. Males congregate at hill tops where they patrol territory for females. It is thought that this allows to butterflies to concentrate themselves for higher breeding potential. This might help explain why there are so many butterflies on grassy hilltops next time you find yourself surrounded!

A female on the host plant called Sweet Fennel. Sweet Fennel is a naturalized invasive from Europe. It is related to carrots, parsley, and other plants within the same family. it is widely distributed and has proved advantageous for the Anise Swallowtail which would otherwise be faring fare worse in our ever developing world.




To fly or not to fly

Laying eggs....and the cycle begins again!

Absolutely fascinating.
The superb pictures speak for themselves, number 3 being my favourite.
A pat on the back for dedication.
