Bagworms

”pine cone” pod
Location: Southern MO (central), just north of AR
February 4, 2012 2:29 pm
Dear Mr. Bugman,
I have just moved into a new home and hanging from the shrubs outside are little pods about 2” long and 1” wide. They look just like a seed pod and I didn’t notice them at first until I found one hanging from my deck, attached with a type of silk.
Upon further inspection, I found tons of these little pods hanging from every shrub in the yard. I have attached a picture and am immensely curious as to what they are. If you could let me know, I would be quite grateful!

Bagworms

Hi Alden,
These are the cocoons of Bagworms, a species of moth in the family Psychidae.  The caterpillars of the Bagworms begin life constructing a small bag which increases in size as the caterpillar grows.  The caterpillar eventually pupates and overwinters in the bag.  Female Bagworm moths are flightless and never leave their bags.  See BugGuide for additional information.

Winter Cutworm

Dear Mr. Green,
Your caterpillar is a Winter Cutworm,
Noctua pronuba, the larva of the introduced Large Yellow Underwing according to BugGuide.  The Winter Cutworm is native to Eurasia, but it is now found in much of North America.

Hornworm from Australia

Hi bugman,
We found this little guy roving around our back deck, celebrating Australia day in style. It was a slightly brighter orange colour than the photo shows. Just wondering what it might be? Obviously some kind of hornworm but I couldn’t see any entries already on your site depicting something that looked the same.

Hornworm: Theretra latreillii

Hi Bridget,
We quickly identified your caterpillar as a Hornworm in the family Sphingidae, but we had to expend some effort to properly identify it.  There are many possibilities of Sphingidae on the Butterfly House website, and the thumbnails are often so small that we need to visit the individual pages.  At first we thought we had identified your caterpillar as
Hippontion celerio, but the Butterfly House images show a much more delicate caudal horn.  A much better match is  Theretra latreillii on Butterfly House, which states:  “Normally the eyespot is hidden by a fold in the skin of the first abdominal segment, and the spot is only displayed when the animal is disturbed. Indeed when the skin is folded, the head and prothorax look like the upper jaw, and the first set of legs like the lower jaw, of some much larger beast, which may deter predators.”  The Brisbane Insect website identifies the adult as the Pale Brown Hawk Moth.

White Stemmed Gum Moth Caterpillar

Hi Bill,
After some searching, we determined that your caterpillar is a member of the family Anthelidae.  According to the Encyclopedia of Life:  “a small family of moths restricted to Australia, New Guinea and the adjacent Aru archipelago. At present the family comprises 74 species in 8 genera described from Australia (Edwards and Fairey 1996) and 20 species from new Guinea in one endemic genus and one genus shared with Australia. However, numerous distinct species have already been identified as undescribed in museum collections such as the Australian National Insect Collection (ANIC).”  Some taxonomists consider them to be closely related to the Lappet Moths and Tent Caterpillars.  We eventually identified your caterpillar as
Chelepteryx collesi, the White Stemmed Gum Moth on the Butterfly House website where we learned that “This Caterpillar is a great hazard to people climbing Gum trees. Scattered over its skin are tufts of long stiff reddish hairs, which are strong enough to penetrate human skin. When they do, they are very painful, and difficult to remove because they are barbed and brittle.”  Another bit of information from Butterfly House is:  “It is also one of the largest Caterpillars in Australia, growing in length to about 12 cms. Some trees where they may be found most years in Leichhardt are known by local school-children as ‘sausage trees’ because the Caterpillars look from the ground like sausages growing in the trees.”

Hi Daniel
Thank you so much for this information.  I have many friends here and overseas that are interested.
A great service that you provide.
Best wishes

Case Bearing Moth Larva

Dear Ray,
This is such a wonderfully detailed image of a Case Bearing Moth Larva.  While they might be considered as Household Pests that could damage organic fibers like wool, they are most likely benign and feeding off shed pet hair, human hair and other organic debris like food crumbs in the home.  The case is made of silk and incorporated particulate matter.

WOW, That was a fast response, Thank you for clearing that up. we called it a flounder bug., left it alone last night as we went to bed, When we woke up she was gone..
thanks again, great service you have.
Have a great day.

Common Palmfly

Dear Cassia,
Thank you so much for submitting your photos of a Common Palmfly Caterpillar and adult Butterfly,
Elymnias hypermnestra agina.  We were able to locate a link on the Butterflies of Singapore website where it is stated: “Field Observations of Butterfly Behaviour:   The Common Palmfly is the most widespread species of its genus in the Indo-Australian region. Locally, it is also a rather common species with widespread occurrence across multiple habitats. Typically the adults are shade-loving, and usually sighted flying along the edge of vegetated area and in the vicinity of a clump of palm trees. The adults have the habit of puddling and visiting flowers for mineral and energy intakes.”  The information provided on the Butterflies of Singapore websiteis very comprehensive, including a list of known larval food plants in the palm family like the cocoanut palm and fishtail palm.

Hey guys.
Found this Caterpillar today eating my Orange Tree leaves. Like to know what this is and if it’s a thread to the tree or not.

Orchard Swallowtail Caterpillar

Dear Michael,
This spectacular caterpillar is that of an Orchard Swallowtail,
Papilio aegeus, and we confirmed that identification on the Brisbane Insect website.  As you indicated, the caterpillar eats the foliage of orange and other citrus trees, however, the loss of some leaves will not harm the tree appreciably.  The red horns at the front of your caterpillar is a scent organ known as the osmeterium.  It is normally hidden, but when the caterpillar feels threatened by a predator, the osmeterium is displayed along with an odor that is described as disagreeable.

Archduke Caterpillar from Thailand, NOT Slug Moth Caterpillar

Possibly Stinging Slug Caterpillar

Dear Does not matter,
While we could not identify your species, and it is not pictured on the Thai Bugs Caterpillar page, it is our opinion that this is one of the Stinging Slug Caterpillars in the family Limacodidae.  Perhaps one of our readers will have better luck with a species identification.

Hi Daniel and Does not matter:
This appears to be another of those Archduke butterfly caterpillars in the genus Lexias. For comparison, see the previous submission by Steven Gehner that was commented on by myself and Keith Wolfe. I am not sure if it is L. pardalis, L. dirtea, L. pardalis dirteana or something else that is closely related, but it is in there somewhere. Keith Wolfe referred to it as the Black-tipped Archduke (L. dirtea).  Regards.  Karl
