Bug of the Week: November Butterflies and Moths

Here it is the end of November already and we still are seeing caterpillars out and about.

There’s silk, holes and frass on some of the hollyhock leaves.

Those belong to the painted lady butterfly caterpillars, Vanessa cardui. 

Painted lady caterpillars vary a lot in color. This one may be lighter because it is a color variation or maybe because it just molted.

They feed on a range of plants, from thistles to sunflowers, but painted lady caterpillars always have a patch of silk around them.

The adult butterflies migrate this time of year. We often see them feeding on lantana flowers. You can see adult butterflies in this post from November 2008.

Once I finished taking photographs of those, over on the Texas yellow bells, Tecoma stans variety ‘Orange Jubilee,’ I found another sizable caterpillar feeding.

This is a rustic sphinx caterpillar, Manduca rustica. In the past we’ve found them on desert willow and cats claw vine. (You can see an adult rustic sphinx moth in this previous post from the beginning of November in 2014.) They are common throughout the southern parts of North America.

Although it looks a bit lethargic above, it was still able to crawl around.

Actually, it was nice that it was a bit slow. I could zoom in on some of the details.

For example, in this close up of the head, you can see the caterpillar’s eye as the black dot right above it’s black front leg.

At the other end is the spiky tail spine.

Sphinx moth caterpillars often have a “tail,” which is what gives them the common name hornworm.

Caterpillars of painted lady butterflies and rustic sphinx moths in the same week. How cool is that?

Bug of the Week: Monarch Diary

I’ve probably mentioned this before, but one reason to publish blog posts like this is to have a diary of events over the seasons and years.

For example, remember the monarch caterpillar from a few weeks ago?

Now I have a record there were monarch caterpillars active the week of October 18, 2017.

Last week I discovered a newly emerged monarch butterfly drying its wings.


It was only a few feet from where I took the photograph of the caterpillar.

Wouldn’t it be cool if it was the same insect? Or perhaps its one of the caterpillar’s siblings?

In any case, it is a male. You can tell from the scent gland on its hind wing. It flew away shortly afterwards.

Wonder where it is this week.

Have you seen any monarchs?

Bug of the Week: Busy Milkweeds

After posting about the queen caterpillars on our rush milkweeds last week, this week I came across another scene.

Yes, there’s a butterfly and a caterpillar. Do you see what is unusual about this?

Let’s take a closer look.

Catch it yet?

Maybe if you see the caterpillar more closely?

The caterpillar has two pairs of filaments or “tubercles” that look like antennae. That means it is a monarch butterfly caterpillar, Danaus plexippus.

The butterfly is a queen butterfly, Danaus gilippus. The queen caterpillar has three pairs of tubercles and different patterned stripes (see comparison here).

They are life stages of two different species, although they are related.

Yes, our milkweeds are busy this year.
