Hi there,
Wondering if you might be able to help me identify this beauty. Maybe some kind of tent caterpillar? I found a bunch of them eating what I believe are the leaves of the trembling aspen. It just pupated and I would love to know the species so I can know approximately how long it will remain in the pupal stage.
So much appreciated!

Dear Nicole,
These are most certainly NOT going to become Tent Caterpillar Moths, though we understand why you are mistaken.  The Caterpillar and Chrysalis will both eventually metamorphose into lovely Mourning Cloak Butterflies.  According to BugGuide:  “Eggs are laid in groups circling twigs of the host plant. Caterpillars live in a communal web and feed together on young leaves, then pupate and emerge as adults in June or July. After feeding briefly, the adults estivate until fall, when they re-emerge to feed and store energy for hibernation. Some adults migrate south in the fall.”  Because they hibernate as adults, Mourning Cloaks are among the longest lived butterflies and they are among the first to appear in the spring, sometimes flying on warm sunny days while there is still snow on the ground.  Mourning Cloaks are somewhat unusual among butterflies too in that they rarely visit flowers for nectar, instead feeding on tree sap and overly ripe fruit, two good natural sources for sugary fluids that they need for sustenance.  Mourning Cloaks have a large range including most of the northern hemisphere.  In England, the butterfly is called the Camberwell Beauty.

Hi, bugman! Can you help ID this caterpillar? I’ve looked at many pictures today and can’t find it. Thank you!

Dear Donna,
We had to scroll through quite a few Brush Footed Butterfly Caterpillars before we identified your American Lady Caterpillar,
Vanessa virginiensis, thanks to images posted to BugGuide.  According to BugGuide:  “Larvae feed on Cudweeds, Everlastings and Pussytoes – Gnaphalium, Anaphalis, Antennaria.”

My son took these photos of some interesting invertebrates in our campsite. The vegetation is blackberry, rose, and common hackberry for trees.
We would love to know what species these are or any information you could give us.

Dear Barbara,
This is a wonderful image of a Mourning Cloak Caterpillar, and we will be posting it to our site to help our readership identify them in future encounters.  Your other insects are an immature Katydid and an Orbweaver spider.

Hi! my wife and I just got a new puppy, and as we were taking him out to the restroom he saw the attached bugs in our tree. we have noticed them dead on our front porch and crawling on our fence as well. Theres ~100 in the tree. We just need it identified to see if its poisonous and how to rid them of our yard so our pup doesn’t have the opportunity to eat them! Its spring, in southern california, been hot the past week.

Dear kg,
While we do have Centipedes in southern California, your images depict Mourning Cloak Caterpillars, and though they may deliver a slight sting if carelessly handled, they are harmless.  There is no need to eradicate them from your tree.  They may climb to the eaves of your home in groups to form chrysalides.  Mourning Cloak Caterpillars will eventually metamorphose into lovely adult Mourning Cloak butterflies.  Some years, when conditions are favorable, the Mourning Cloak Caterpillars can be quite numerous.  Their local native host is willow, but they have adapted to feeding on the leaves of Chinese elm in California.

Subject: Painted Lady?

Hi, I’m hoping you can help me again.
All three of the photos below were taken in October 2014, in the same plant in Cuernavaca, Mexico (altitude 1580 m). Those caterpillars were all over that plant for several seasons, until eventually there were enough to kill it. The butterflies are also very common. We believe they’re the same species, but obviously are not 100% sure.
From the caterpillar I thought a Painted Lady or Red Admiral, but the chrysalis and butterfly don’t match.
Thanks for any help you can provide.

White Rayed Patch

White Rayed Patch

Dear Peculiarist,
This lovely little Brush Footed Butterfly is a White Rayed Patch,
Chlosyne ehrenbergii, which we identified on Learn About Butterflies where it states:  “The eggs are pale yellow in colour, and laid in batches of up to 200, on the underside of leaves of the foodplant, Buddleia.”  We believe the leaves in your images are of butterfly bush or Buddleia, so the caterpillar and chrysalides are most likely the immature stages of the White Rayed Patch.  We will check with Keith Wolfe for verification as we cannot seem to locate images of the immature stages, though the appearance of the caterpillar and chrysalides are consistent with other members of the genus.

Hola Daniel,
Would you please ask “Peculiarist” to kindly send me (OK to share my email address) ONLY the caterpillar photo at FULL size?  The pupae look good for C. ehrenbergii, but the larva appears a little different.  Muchas gracias!
Saludos,
Keith

Hi Daniel,
As I was updating my page I noticed that this is the same caterpillar I sent before (my photo folders are a bit of a mess, and I had this duplicated in another folder), that was tentatively identified as a Pine Moth caterpillar. They do look alike, but I think with the extra information you have in these three photos White-rayed Patch is a more likely match. The food tree matches.
Thanks for your help, and I’ll be more careful in sending the most complete information I can in the future.

Buenas noches James and Daniel,
Muchas gracias for the corroborating larval image.  Being endemic to Mexico, life-history photos of “Mariposa parche negra” are difficult to find online, so here are some examples . . .

Hi Bugman,
We found another caterpillar. This time, it one about an inch and a quarter long and about a quarter inch wide. But what is really cool is its coloration – shiny, bright gold. My photo just doesn’t do it justice. I hope you can tell us what kind a caterpillar it is.
Cheers,

Nymphalidae Chrysalis

Mexican Fritillary Chrysalis

Dear Winjama,
This was once a caterpillar, but now it is a Chrysalis of a butterfly in the family Nymphalidae.  We have not had any luck finding any matching images.  We will contact Keith Wolfe to see if he can provide a species name.
