Monarch Butterflies Roost at Pismo Beach

Location:  Pismo Beach, California
January 26, 2011
Hello Daniel,
I continue to thoroughly enjoy your site — especially here in central Minnesota in January.
In November, my family and I learned the monarch butterflies west of the Rockies spend their winters in coastal California.  We’ve wanted to visit the sites “our” monarchs use in Mexico, but that’s very expensive and currently too dangerous.  I know yours is not a travel site, but we learned of this place quite by accident, and I’m sure other bug nuts would appreciate learning about Pismo State Beach, and the other sites there.  Perhaps you need to add a “travel section” to WTB.
I could tell you much more about our trip to your state.  Beyond seeing thousands of monarchs, it was very interesting to see how many of the butterflies there are tagged.  We observed four or five different-colored circular tags, and many butterflies marked by coloring in a cell on the rear right wing with a Sharpee marker.  This is done by those keeping track of the number of butterflies using the site (around 20,000).
Anyway, the Pismo site is very accessible to anyone and easy to find.  The butterflies are there from November through February, depending on the weather.

Thanks for your continuing excellent work.

Monarch Butterflies Roosting

Hi Don,
Thanks for your wonderful letter.  It is interesting that these Monarchs are roosting in a eucalyptus tree which is not native to California.  Though I have never visited one of the roosting sites, I did have the distinct pleasure of seeing migrating Monarchs roosting in a tree in Roosevelt Park in Youngstown, Ohio as a child.  It was an awesome sight.

Hello again, Daniel.  Thanks for your quick reply.
A graduate student studying the Pismo monarchs told us the monarch used to roost in cyprus trees there.  But the pioneers cut those trees down, and planted eucalyptus.  The “new” trees leaves are glossy, and she told us the butterflies have a hard time getting a grip, sometimes falling right off.  The State Park is trying to re-establish some cyprus there.
Interestingly, the grad student also said when they are counting the butterlfies, they have to double their estimate for those clusters on the cyprus, because the monarchs group so much more tightly on their original tree species.
Thanks again.
Don

This little beauty fluttered into my van last summer. Is it an Eastern Swallowtail butterfly? Thank you!

Tiger Swallowtail

Hi Cheryl,
There are several other species that look very similar to the Eastern Tiger Swallowtail,
Papilio glaucus, including the Canadian Tiger Swallowtail, Papilio canadensis.  To further complicate identifications, the ranges of the Eastern and Canadian Tiger Swallowtails overlap in places, including Maine.  We cannot say for certain which species you have, but the blue markings on the hind wing indicate that this is a female.

Cruiser from Malaysia

Orange Cruiser Butterfly of some sort?
Location: Pulau Tioman, Malaysia

This is another that I ran across in Malaysia this summer. Looks like it is a Vindula of some sort, but all the pictures I’m seeing aren’t as orange, and don’t have as many eye-spots.
Searching Orange Cruiser gets me more bicycles than bugs.
A splash of color for winter, anyway.

Cruiser

Dear Bert,
Your identification is correct.  This is a Cruiser,
Vindula dejone, which we identified on the Butterflies of Malaysia website.  There is often individual variation within a species, and your specimen may appear especially vivid if it is a newly metamorphosed individual that has not lost any of the scales on its wings yet.  This individual on FlickR is showing some wear and tear and is not as brightly colored as the individual in your photo.

Possibly Large Orange Sulphur from Hawaii

Maui Cloudless Sulphur
Location: Waiehu, Maui

Aloha – found this bright one flitting about the shoreline in Waiehu. He settled on a naupaka kahakai which almost matched his coloring. It was very sensitive to my presence, so this is as close as I got without spooking him away. Being at the beach, with the bright yellow coloring, he stood out against the green naupaka and the sand colors.

Possibly Large Orange Sulphur

Dear Eliza,
Whenever we post a letter of a new species, or a familiar species in an unfamiliar location, we try to link to some other site to provide a reference.  We went to the Butterflies of Hawaii Website and it indicates that the Large Orange Sulphur,
Phoebis agarithe, is a newly recorded species that is known from Maui.  The University of Hawaii Insect Museum website does not picture any species in the family Pieridae.  We also found a Webshots Butterflies of Hawaii website, but again, the only Sulphur pictured is the Large Orange Sulphur.  Perhaps the Cloudless Sulphur, Phoebis sennae (see BugGuide), has also been introduced to Hawaii, but we cannot locate any internet reference to support that.  We are more comfortable identifying this as a Large Orange Sulphur, but there isn’t enough detail in your photograph to be certain.

Aloha Daniel -
Thanks for the speedy reply, as usual.
Hmmmm. What info do you need to further clarify – the size of the leaf it was on? Or?
Couldn’t get any closer – it bolted once from that area and came back.
Don’t know if it will be back there again and I don’t get over there often.
We certainly have the food sources it likes as an adult – hibiscus and bouganvilla are plentiful.
Happy weekend ~
Eliza

Hi Again Eliza,
If you compare the description and images of the Large Orange Sulphur on BugGuide with those of the Cloudless Sulphur on BugGuide, you will see that the two species are quite similar, hence our reluctance.  Our identification was based on the Large Orange Sulphur being well documented on Hawaii and there being no reports of the Cloudless Sulphur on Hawaii that we can find.  With that said, it is entirely possible the the Cloudless Sulphur has been introduced to Hawaii.

Appreciate the information, Daniel.
Understand now what I was not grokking.
Too bad that this yellow butterfly is considered ‘orange’.
If I can take a photo one with its wings open, I’ll send that on. But who knows when that will be. This is first time I’ve ever seen this butterfly, much less have a camera at hand.
Happy Sunday evening~
Eliza

Again Eliza, we cannot totally discount that this may be a Cloudless Sulphur.  We did need to increase our vocabulary by researching “grokking.”

Stranger in a Strange Land – Robert Heinlein is the source of grok, Daniel.
I do understand why you lean towards the Orange vs the Cloudless. Totally reasonable deduction. Truly… not a problem that I was in error! Always happy to have clarification when there’s a piece of data I am not aware of.

Life (and death) in a milkweed patch
Location:  Manitoba’s Birds Hill Provincial Park, Canada
December 28, 2010
Hi Daniel:
Every July tens of thousands of people descend on Manitoba’s Birds Hill Provincial Park for one of Canada’s, and North America’s, oldest and largest folk festivals (we haven’t missed it for more than 30 years!). In 2006 I discovered the most impressive milkweed patch I have ever seen, wedged between a parking lot and an oak forest, and was thrilled with the abundant and diverse bug life I found there. …  If you or any of your readers are interested, I have uploaded a collection of photos taken at this location since 2006 (with more to follow next year, I am sure). I am still working on some of the identifications and I am not certain about some of the ones I have inserted, so any comments or suggestions would be welcomed and appreciated. Regards.  Karl

Go ahead and borrow anything you like, or let me know if you have anything specific in mind. I have thousands of photos that I have been meaning to organize and perhaps upload, but I just haven’t been able to find the time. Perhaps next year.  Have a great new year! K

Tiger Swallowtail Caterpillar

We saw this caterpillar hiking in Vermont this fall and we are wondering what it is and what it will look like as a butterfly or moth.

Tiger Swallowtail Caterpillar

Dear interested,
Your caterpillar is one of the Tiger Swallowtails.  There are several species with ranges that overlap in Vermont, including the Eastern Tiger Swallowtail and the Canadian Tiger Swallowtail.  It is very difficult to tell the species apart.  The caterpillars of both species turn from green to brown or sometime orange just prior to pupation.  You can see a photo of an adult Tiger Swallowtail in our archive.

Identification Please

Dear Bugman,
I photographed these two insects and I need an identification. The first one is of a butterfly that I took in November. At first I thought it was a monarch but the top wing looked different to me. The second photo is of a insect on Mt. Lemmon, Tucson, and it was taken in July of last year. Thank you so much

Hi Harrison,
You were observant to notice the difference between a Monarch and your butterfly, the closely related Queen.  You can read more about the Queen,

Orchard Swallowtail

Hi Gayle,
The Orchard Swallowtail,
Papilio aegeus, in your photo is actually a butterfly.  There is a very nice page devoted to the stages of development on the Brisbane Insect website which indicates that your specimen is a female.  According to Oz Animals:  “The male Orchard Swallowtail has black forewings with an arc of white spots near the tip. The hindwings have a white panel and single small red spot above. The underside of the male wings are black with red and blue spots. The female has black and white forewings and hindwings. The hindwings have blue and white markings.

Hi Daniel
Thankyou for the reply, my husband had heard somewhere that the difference between a butterfly and moth was the way the wings stood up on a butterfly and laid flat on a moth, hence our confusion.
I must admit I have never seen a butterfly so big, my boys and I were quite amazed.  Is it common for it to be so far south of Qld?
Gayle Downey

Hi again Gayle,
Though we are not certain exactly how common it is further south, the range is indicated on Csiro.
