Another success

The polydamas swallowtail was the first swallowtail to visit my garden and instantly became a favorite. They are so incredibly hard to photograph with their wings open, as they are constantly fluttering. I was beyond excited when this newly emerged polydamas swallowtail showed me its full beauty after releasing it into the garden.

he polydamas, also known as the gold rim swallowtail, tailless swallowtail and scientific name Battus polydamas lucayus, lays its eggs on the Dutchman pipe. This is the only swallowtail that lacks the tails at the base of the secondary wings, according to the University of Florida.

This species can be found throughout peninsular Florida, as well as in the Florida Keys. There are some that wander as far north as Missouri and Kentucky.

The polydamas swallowtail’s wings range from 9.2 to 11.6 centimeters.

The female is larger than the males. According to the University of Florida, the males have scent scales, which are hidden on the fold of the inner margin of the upper surface of the hind legs. The scales are “fluted,” releasing pheromones easier. When the mating dance begins, the male will helicopter around the female, all while fanning those chemicals over them.

A favorite

The orange barred sulphur caterpillars are so hard to spot in the Bahama Cassia tree. They really blend in with the leaves, so often times I don’t see them until they have reached the last instar.

A stroll

One day last week I was sitting at my desk working when a monarch caterpillar caught my attention going for a stroll up the window. It was a great distraction from writing articles. The caterpillar found its resting area under the windowsill for its chrysalis.

Both of my giant milkweed are crawling with caterpillars of every instar. My butterfly house has a tremendous amount of activity from caterpillars eating, to creating their chrysalis and emerging. It has been a tremendous few months for these lovely caterpillars and butterflies.

Lovely

The gardens have been a monarch paradise these last few weeks. The garden has every stage of life from eggs to butterflies.

For the Sunshine State, they are seasonal in Northern Florida with low numbers during the spring before exploding by the millions during the late summer and fall. In central and southern Florida, the monarch butterflies breed all year.

According to the National Wildlife Federation, the monarchs are broken down into eastern and western populations divided by the Rocky Mountains. It states that the eastern population is the largest. This population migrates northward. In the spring they leave Mexico and migrate north into Texas and the Southern Plains, through the Northern Plains, Midwest and into the Great Lakes area. And by late summer the monarchs expand into Canada, eastward from its central migratory corridor of the United States through the northeast and southeast states.

The National Wildlife Federation states that the late summer, last generation of monarchs that emerges will delay sexual maturity for migration. This migratory generation can live up to eight months, compared to the typical few weeks.

It’s fascinating to learn about the monarch’s incredible migratory patterns. In Southwest Florida we are blessed with these beauties visiting the garden daily during the winter months as the weather never dips to unbearable temperatures.

Today, similar to many others, the nectar plant of choice is the red penta. We also had a female monarch emerge in the butterfly house, the one that is on the same milkweed plant as the monarch caterpillar.

The orange caterpillar

The gulf fritillary caterpillar will spend up to 16 days eating its host plant (corkystem passionvine), molting, shedding its skin, as it grows larger and larger.

The caterpillars also take in toxins from the passionflower, which are stored and kept in their bodies through turning into a butterfly, according to the Alabama Wildlife Federation.

I am beginning to see a lot more gulf fritillary butterflies flutter about the gardens. I was excited to see a rather large caterpillar resting in the garden near its host plant.
