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.

More Monarch Butterflies

It’s baby time again in the butterfly nursery at our house! In a June blog post  I told you about the thrilling visit by a female monarch to our garden, and showed you photos of her laying an egg on our milkweed.

The first monarch emerged this weekend!

His empty chrysalis is on the left. His sister is ready to emerge – we could tell because her chrysalis became transparent and we could see the pattern of her wings through it.

I made a poster and card of the life cycle of the monarch butterfly.

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.

Click here to see my post about the monarch butterfly that left that egg.

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.

Ladybug Ladybug

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!

Anise Swallowtail Butterfly bonanza

It’s a banner year for anise swallowtail butterflies, at least in our garden! A few weeks ago we saw a butterfly fluttering around the fennel plant in the back garden, and sure enough we found 13 eggs. We brought them all in and they’ve started to emerge.

We’ve also had some chrysalises incubating for a year or more, and some of them finally decided to emerge as well. Three of the butterflies came out yesterday and four today.

Anise swallowtail butterfly newly emergedWe check the fennel periodically for eggs and babies, and usually find them when they’re small, but this caterpillar eluded us until he had gotten quite large.

Anise swallowtail caterpillar on fennelThis is an extreme closeup, he’s actually a bit over an inch long. Anise swallowtail butterflies, in our area, mostly use fennel for their larval host. It’s plentiful and grows much more easily than the native host, yampah. The problem is that people often cut it down because it gets so large and rangy. Now that you know the beautiful butterflies that rely on the plant, please don’t cut it down until the end of the summer! Want to learn how to raise the butterflies yourself?

Pipevine dreams

One of my favorite local butterflies is the Pipevine Swallowtail (Battus philenor). Here’s a photo of one that we raised a few years ago. Strikingly dramatic, it has black wings fringed with large white spots.

Pipevine Swallowtail butterflyThe underside is equally as exciting — I like Wikipedia’s description: “The underside of the hind wing has seven orange submarginal spots surrounded by iridescent blue.”

Its host plant in our area is the Pipevine (Aristolochia), also known as Dutchman’s Pipe. Once you see it you’ll understand the name:

Dutchman's pipe

We’ve been growing pipevine in a few spots in our garden for several years, but haven’t yet been lucky enough to attract a butterfly to lay eggs on any of them. The vine in the front garden put out a profusion of pipes last week. This photo shows one string of them – there are many more pipes zigzagging up the tree that the vine is twined around.

Pipevine plant

The plants need to get really large to attract the female to lay eggs. We have raised caterpillars from eggs that we rescued, and they ate the pipevine leaves voraciously. We had to forage to find them enough to eat!

This is an “artsy” piece I made from my photo of a Pipevine Swallowtail on a buddleia flower.

Pipevine swallowtail butterflySo this year we’re having pipevine dreams that a butterfly will visit our garden and lay some eggs. If you see one, please send her our way!
