Mating Monarch Butterflies

Dear Jeff,
Thank you so much for sending your gorgeous images documenting the complete life cycle of the Monarch butterfly.  It is going to take us a healthy chunk of time to format all your images and set up the posting properly so we are just starting by posting an image of a mating pair of Monarchs.  The male is the individual with the open wings, and the female appears to have been tagged because her hind wings have what appears to be an inked marking.  We can also identify the male, according to BugGuide, because:  “Males have scent-scale patches on hindwings, prominent when wings are open, and just possible to see when wings are folded.”  Over the course of the day, we hope to get all your excellent images added to the posting.

Male Monarch

Hi Daniel,
I don’t have complete life cycles for the rest of the butterflies that have graced our back yard, but I’ll send in what I have.  Regarding the Marine Blue, I can resend them with the other pics.  The ones I sent seemed to have unusual coloring.
By the way, I want to thank you for so graciously accepting my pictures.  It makes me happy to be able to share them.

We are interested in Finding out what kind of caterpillar this is.

American Lady Caterpillars

Dear Amy,
These American Lady Caterpillars,
Vanessa virginiensis, will eventually transform into a lovely orange American Lady butterfly.  According to BugGuide:  “Larvae feed on Cudweeds, Everlastings and Pussytoes.”

I so wish I could send you something cool, but all the tents have been invaded and they are all gone. I think the Mockingbirds got to them. We had a nest of them in our climbing rose with 3 fledglings all about. Maybe we’ll get them again sometime!

Baltimore Checkerspot Caterpillar

Dear Randall,
We were able to identify your Baltimore Checkerspot Caterpillar,
Euphydryas phaeton, thanks to images posted to BugGuide.  According to BugGuide:  “The primary larval food source is turtlehead (Chelone glabra), although recent studies have shown that the caterpillars will eat a larger variety of plant species including English plantain (Plantago lanceolata), a common yard weed.”  The adult Baltimore Checkerspot is a very lovely butterfly.

Thank you so much.
This helps and clearly is the match.
Feel free to use the photos I sent if they could be helpful for you guys.

I have a plant that just popped up in my garden and think it’s a lamb’s ears. Each tip of the tallest 5-7 branches have been folded up into caterpillar homes. See picture… Do you have any idea what they might be?
Thank you!

American Lady Caterpillar

Dear Judy,
This distinctive caterpillar is an American Lady Caterpillar,
Vanessa virginiensis.  According to BugGuide:  “Larvae feed on Cudweeds, Everlastings and Pussytoes – Gnaphalium, Anaphalis, Antennaria.”  BugGuide also makes reference to the caterpillars making “leaf shelters” and there is a nice image on BugGuide with the caption “The larva weaves the leaves together and feeds inside the shelter.”

Thank you Daniel,
That’s exactly what they are doing – “weaving” for shelter. I see no signs of them feeding on any leaves. I hope they survive. I look forward to seeing them as butterflies. 🙂

Dear Judy,
We would love any images you can send of chrysalides or adults once they emerge.

Hi Bugman,
Here’s the next set of pictures. Hope you enjoy them.

Mating Gulf Fritillaries

Dear Jeff,
It is going to take a chunk of time to correctly edit the posting to contain your awesome images depicting the life cycle of the Gulf Fritillary,
Agraulis vanillae, a common Southern California butterfly.  We have decided to begin the posting with your awesome image of a pair of mating Gulf Fritillaries, a logical place to begin a life cycle, and we will add to the posting as we reformat your images. This has prompted us to initiate a new tag of Buggy Life Cycles to house both this and your previous Anise Swallowtail documentation.

Hi Daniel,
This is the second time you’ve spotted a parasitic wasp in one of my pictures.  Is there anything I can, or should, do about this?  I understand the wasp has as much right to exist as the butterflies, but I can’t help feeling protective over the caterpillars.
Thx, Jeff

Gulf Fritillary Chrysalis

Sorry Jeff,
We can’t think of a way for you to protect the early stages of butterflies from parasitoids unless you raise the caterpillars in a container with a fine mesh screen.

I am a hopeless butterfly enthusiast who came across this interesting caterpillar crawling along the
paved trail in our state park. I am familiar with the common butterflies found in our area, but my
research provided no matches for this larva. It was clearly in the wandering stage, seeking out a place to pupate. I hope you will be able to solve my little mystery. I would love to know to which
species it belongs! Many thanks in advance.

Our Automated Reply:  Thank you for submitting your identification request. Please understand that we have a very small staff that does this as a labor of love. We cannot answer all submissions (not by a long shot). But we’ll do the best we can!

In the interest of not wasting your valuable time, I want to let you know that I
was able to identify my butterfly larva.  It is a Mourning Cloak caterpillar!
Thank you for the great work you do!

Mourning Cloak Caterpillar

Dear Kathy,
We are thrilled to post your image of a Mourning Cloak Caterpillar.  Theyy do wander in search of a suitable site to undergo metamorphosis, and we have several images in our archive of Mourning Cloak chrysalides under the eaves of homes.
