Anise swallowtail butterflies return

The calendar says it’s summer, but my weatherman (aka George) observes: Brrrrr … . Happily, despite our fog and chilly temps, the Anise Swallowtail butterflies are here on schedule. I haven’t seen any adults visit the garden, but they’re leaving precious yellow eggs on the fennel. The egg on top was probably laid today, the one with darkening bands was likely laid several days ago. This is an extreme closeup shot – the eggs are smaller than the head of a pin.

I took this photo in 2013 of a female laying an egg (ovipositing) on the same fennel plant.

We keep the eggs and caterpillars inside in a net cage where we feed them and keep the chrysalises safe until the adult butterflies emerge. We also rescued several caterpillars from a plant in our neighborhood that has been cut down in previous years. This guy just shed his skin (on the right).

So far one adult has emerged.

When the sun finally came out I put her onto a lily plant on the deck, and after a minute or so she happily flew away.

Cats and cats

What do feral cats and butterfly caterpillars have in common? Not much beyond linguistically – some people use the affectionate term “cat” to mean caterpillar. Other than that it gives me an opportunity to tell you about my weekend. I was helping George feed one of his feral cat colonies in an overgrown field when I saw an anise swallowtail butterfly on a mallow plant. The helping part ground to a halt while I took photos, but George didn’t complain.

I had brought the camera to get some photos of the cats. They know him and come around when he brings their food and water.

Some hold back until he steps away.

Others are so friendly it’s obvious they were house-cats, mostly likely abandoned when people lost their homes. Shameful, even so.

After we fed the cats I found one swallowtail butterfly egg on a wild fennel plant. This time of year there should be many more.

I hadn’t found any eggs on our garden fennel yet, but I was curious after finding the one in the field, so I checked – no eggs, but one large caterpillar!

We’ll let it make its chrysalis in our butterfly nursery, and then release it after emerging. I’ll keep you posted! Just a reminder if you have wild fennel growing on your property – yes, I know it gets rangy and out-of-control, but if you need to cut it down before it dries out, please check for eggs, caterpillars, and chrysalises. Making your yard look neat could cost the lives of many of these beautiful butterflies.

So my wish: more caterpillars, no more abandoned cats!

A Butterfly Born on the 4th of July

We’re still finding anise swallowtail butterfly eggs on the fennel in our garden. And ta .. daaa… the first of the recent batch we’re raising emerged today. Born on the Fourth of July; more orange, yellow and blue than red, white and blue, and with stripes!

The caterpillar at the top of the enclosure looks like it’s ready to form its chrysalis. And here are younger sibling caterpillars, still eating away.

We’ve been gathering fennel around the neighborhood, because our plants are starting to be pretty sparse after feeding at least 30 growing caterpillars!

So which do you think came first, the butterfly or the egg? I don’t have an answer to that old conundrum, but to bring the story full cycle, I just took this photo of one of the anise swallowtails depositing eggs on the fennel in our garden.

Since we’re also finding monarch butterfly eggs on our milkweed, I took an extreme closeup photo of a monarch butterfly egg (on the left) and an anise swallowtail egg (on the right), to compare their sizes, and with the head of a needle included for scale.

I’ve said it before, and I’ll say it again – if you have to cut down the fennel that’s growing on your property, please check it carefully for eggs, caterpillars, and chrysalises first. You could be killing an entire generation of anise swallowtail butterflies.

Early Summer Garden

Welcome to June-time in our garden. As the roses fade we have some other wonderful flowers blooming. The stream orchid (Epipactis gigantea) is a California native orchid. Here’s a closeup; the flowers are only about a half inch.

The flowers of the Soap Plant (Chlorogalum) are also extremely small. Bumble bees love these; I’m always amazed to watch the fat bees light on and weigh down the delicate flowers.

A trill from our guard-hen, Maureen, alerted us to a visit by Bambi. He was waiting in our neighbor’s yard for us to leave so he could graze on George’s delicious flowers and plants. Last week he ate nearly every leaf off our poor peach tree. Guess the fruit wasn’t ripe enough for him, he left us those.

Anise swallowtail butterflies, probably the ones that we raised and released in the past few months, have returned to lay eggs on our fennel. We caught this one flitting about, and I managed to get a photo of her leaving some eggs.

Finally, the hummingbirds are back, and happily visiting our flowers and feeders.

What’s growing in (and who’s visiting) your garden this summer?

The Cycle Begins

Over the last few weeks more than ten of the anise swallowtail butterfly chrysalises that we’ve been sheltering in our butterfly nursery have emerged. These three beauties emerged in one day. We waited for the weather to improve, and took them out to the deck to release them. You can also see two batches of chrysalises still waiting to emerge. For some reason, possibly protection, they sometimes make their chrysalises right next to or on top of one another.

Anise swallowtails can remain in the chrysalis stage for years, and some of the ones that emerged have been gestating for more than two years. Every time we release a female I ask her to come back to our garden to lay eggs.

The native plant that anise swallowtails lay their eggs on is called yampah. George has some yampah in a pot, but it grows very slowly. A couple of years ago we were thrilled to find some eggs in our yampah. Here’s a picture I took. The egg is the tiny yellow dot near the center of the picture.  It’s about the size of the head of a pin.

Since yampah is very hard to find in the wild around us (not much wild left hereabouts  …), the anise swallowtails in our area have turned to the fennel plant to lay their eggs and as their larval food source. Fennel grows prolifically in vacant lots and along the highways. Many people cut it down as it gets rangy later in the summer, which is too bad, because they’re killing hundreds of swallowtail eggs and caterpillars. Anyway, to the point of this post .. drum roll please … I found three eggs on our fennel this morning! Here’s one.

We released this female last Tuesday, maybe they are her eggs?

Have you seen many butterflies in your garden yet? Do you plant milkweed for monarchs or other plants to attract and feed butterflies?

I’ve told you before that George and I rescue the anise swallowtail caterpillars and eggs that we find on fennel plants. The fennel gets rangy this time of year and many people cut it down, not knowing that they’re killing caterpillars. We bring the eggs and caterpillars inside, feed them fennel until they pupate into chrysalises, then release them after they emerge as adult butterflies. I rescued a large caterpillar and five eggs the other day from a parking lot in Berkeley, and the eggs have now all opened. This one is about 2 mm long.

Today while searching some fennel near our house I found another insect – ladybugs – happily wandering around the fennel flowers, probably looking for aphids to feed on. Here’s one with a few of the characteristic black spots, and very intense red-orange color.

Another one’s spots were barely visible, and its color was much less red.

This one was moving from one flower to another.

Does fennel grow on your property? Please make sure to check for butterfly eggs and caterpillars, and for other helpful insects like ladybugs, before you cut it down.

Found in the garden

If you follow my posts, you know that George and I raise and release butterflies. George plants larval hosts to attract egg-laying females to the garden, and when we’re lucky we find the eggs and bring them inside to raise them. Most recently we’ve had a flurry of anise swallowtail butterflies visit the garden and lay eggs on the fennel. We’ve released about 10 of the butterflies in the past few months. We usually find the tiny eggs, which are about the size of the head of a pin…

… or the caterpillars when they’re relatively small (these guys were about a half inch long).

Today, I found a caterpillar which had thus far escaped our not-so-eagle-eyes. It looks to me like it’s ready to form its chrysalis. I brought it inside to protect it from predators and bad weather. I’ll let you know when it emerges.

Anise swallowtail butterfly caterpillar on fennelI recently shut down my smugmug site, where I had galleries of my photos showing the entire life cycle of the anise swallowtail butterfly and the monarch butterfly. I am reconstructing those on my website and will let you know when they’re up. Hopefully letting you know that will motivate me to get it done more quickly!
