Bug of the Week: Gulf Fritillary Butterfly

This week my friend Debbie called and invited me to visit her butterfly garden. Sure enough, when I arrived there were several species of butterflies flitting throughout her yard. By far the most common were the bright orange and silvery white gulf fritillary butterflies. I also saw numerous skippers and a few giant swallowtails, as well as a yellow sulphur butterfly.

It was hard to get the active gulf fritillary butterflies to sit still long enough to get a photo. The adults were searching her yard for the numerous passion vine plants she had planted. The adults lay eggs on the plant and the caterpillars use it for food. Can you guess what happened to this one?

Here’s an adult apparently laying eggs on a piece of passion vine. Note the remnant of a chrysalis hanging to the left of the butterfly. Can you see the beautiful silvery-white patches on the undersides of the wings?

Debbie’s passion vines are in various stages. Some have no leaves left from all the caterpillars that have been feeding on them in the past. If you are going to have brilliant, vibrant butterflies, you’ll have to accept that your plants may look a bit raggedy. The vines are around an aloe plant in a pot.

She has a couple of different passion vines, with different shaped leaves. Here is one that still has leaves.

Here’s another with an empty chrysalis.

The passion vines have gorgeous, very unusual flowers. I couldn’t find flowers this week, but here is one I shot at the National Botanical Garden a few months ago.

Here is a link for passion vine flower photos of several different species.

I did find a fruit.

Debbie opened one and showed me the unusual seeds inside. Cool!

Here is a cute skipper that was more willing to pose for me than the fritillaries. The skipper caterpillars feed on various grasses and they are quite common. Sometimes they are mistaken for moths because of their drab brown color.

This experience made me realize how very rewarding butterfly gardening can be. We were able to see and talk about so much in just a short period of time. With a few well-chosen plants, some sun, water and patience, Debbie has created a lively and enriching environment.

Debbie, thanks for sharing.

More About Seed Bugs

After writing my post on Wednesday about seed bugs, I sent it down to the Great Bug Guru and Swell Guy, Carl Olson, at the University of Arizona. Carl was nice enough to straighten me out on the scientific name of the bug in the photo. He also let me know that there is similar bug that he has been hearing a lot about here in Phoenix.

Here is a photo of the bug he’s been getting calls about, Neacoryphus lateralis.

Carl was also nice enough to send me a photo of the small milkweed bug, Lygaeus kalmaii. This is the species that may also occur on milkweeds, and also has a white spot (actually a pair of white spots), on the back of its wing.

Bug of the Week: Seed Bug

This morning it was a bit difficult to find a bug for bug of the week. Can you guess why from this picture?

raindrops

Woo, woo, it is raining here. Rain is a novel event, and all the insects apparently have sought shelter. I knew where to look, however, to find an insect that would be still out. There is always something happening on the desert milkweed, and this morning was no exception. Here is our bug this week, captured quickly before it started to rain again.

The bright red bug shown is commonly called a seed bug (Oncopeltus sanguiniolentus). It may resemble the boxelder bug found in other parts of the country, but it lacks the black bars on the red section (top) of its wings.This species has one white dot in the black part (bottom) of its wings. Another species that has the black bars in the red, but has two white dots in the black is the small milkweed bug, Lygaeus kalmii. (See photo in newer post). To paraphrase Dr. Seuss, “what a very lot of bugs there are!”

It is amazing that there are so many insects feeding on the desert milkweed. The sap of milkweeds contains both rubbery latex and poisons. Insects like queen and monarch caterpillars, yellow oleander aphids and these milkweed bugs have ways to deal with it. In this case the bugs avoid the latex-carrying channels with their straw-like mouthparts.

If there aren’t any milkweeds available, these versatile bugs also feed on the seeds of various plants.
