Cloudless Sulphur Caterpillar Camouflage

Image
Cloudless Sulpur caterpillars use camouflage for protection as they feed on Cassia trees. During the summer months, the caterpillar's green color matches the leaves of Cassia plants. In November the Cassia becomes covered in beautiful yellow flowers. As the caterpillars eat the flowers, they begin to turn yellow. This yellow color provides perfect camouflage while the caterpillar crawls among the blossoms. This Cloudless Sulphur caterpillar has a greenish hue. It has been feeding on Cassia leaves. Cloudless Sulphur caterpillars green color provides the best camouflage during the summer months. The caterpillars will begin turning yellow only in the fall months when the Cassia tree blooms and the caterpillar feeds on the yellow flowers. The arrow points to the silk created by the industrious creature. The silk secures the bud to the stem and keeps it from falling with the extra weight of the caterpillar. One day in my garden, I ...

Diseases, Defects, and Injuries of Butterflies

Image
In nature, butterflies with defects soon become part of the food chain. When raising caterpillars and butterflies inside an enclosed area, injuries and disease can be observed first hand.  Some of the problems a caterpillar may encounter are bacterial diseases, defects during development, or falling before the butterflies wings are completely dry. Watching a butterfly struggle as it tries to overcome its impairment is saddening. I have also learned that in the wild the survival rate of an egg making it to a butterfly is less than 10%! By rearing caterpillars in captivity this can be reversed so that up to 90% can survive to be butterflies.  Bacterial Infections Active caterpillars crawled over my soft chrysalises causing punctures . Raising caterpillars in captivity has many benefits, but it has disadvantages as well.  I have had as many as forty caterpillars in one container. The result was that the active caterpillars began to crawl ove...

The Uninvited White Peacock Butterfly in My Bedroom

Image
  I walked in my bedroom and almost stepped on an insect. Not just any bug, but one of my White Peacock butterfly! At first I thought my sister had played a trick by putting a dead butterfly on my bedroom floor, but after closer examination I realized it was real. I have found caterpillars crawling in our house, but never a live butterfly. It must of taken a ride on my back entering the house, after my morning in the garden. It was quite an adventure with my siblings and I chasing after a loose butterfly in the house!   The next day the sun illuminated my room, and the butterfly began to fly around my room. With my hand made butterfly net I finally caught it! I took it outside and released in my garden where it belongs. The butterfly’s proboscis had not completely fused together when I observed it. The butterfly’s proboscis is two separate pieces when it first emerges from the chrysalis. After curling and uncurls the long drinking tube, it becomes connect...

Milkweed Seed Pods

Image
  Tiny drops of dew collected on my milkweed leaves and on the webbing that had been created by tiny spider mites that morning. Spider mites are pests of Tropical milkweed plants. They ingest sap out of leaves decreasing the nutrition needed by Monarch caterpillars and can attack young caterpillars. To remove these tiny red spider mites try spraying infected plants with water. Be careful not to spray off Monarch eggs also! When my spider mites get out of control, I trim back the milkweed and have to dispose of infected leaves. I haven’t trimmed back my milkweeds yet because they are covered in large milkweed seed pods that will soon open. Each flower that is pollinated, will produce one large seed pod. Sometimes two pods can come out of on flower. The seed pod will begin to darken before opening. The crunch of the seeds can be heard when the pod is squeezed.    The seed pod will begin to crack to reveal crisp brown seeds. I counted 110 in just on pod and I have...

Long-tailed Skipper Life Cycle

Image
  The Long-tailed Skipper butterfly is a large skipper that is an attractive addition to every garden. The Long-tailed skipper is easily recognized because of the long “tails” that protrude from its wings. There are thousands of different skippers that live worldwide. Skippers are smaller than other commonly seen butterflies and many feed on grass. Skippers were given this name because of their appearance to skip as they fly. The Long-tailed Skipper's caterpillars feed on plants in the bean family. One of their host plants is the Butterfly Pea plant which has beautiful purple flowers. They often lay they their eggs on bean plant in agricultural fields. Sadly it is thought of as a agricultural pest by bean growers along the southeastern U.S. I welcome the Long-tailed Skipper in my “Secret Garden” and enjoy taking photographs of this unique creature. A female Long-tailed Skipper deposited eggs on my butterfly pea plant while visiting. Long-tailed Skippers often lays th...
