Buckmoth Caterpillars

Hi Carson,
These sure look to us like Buckmoth Caterpillars, possibly
Hemileuca maia based on this BugGuidephoto.  Your email did not indicate if this is a recent sighting.  We suspect it was earlier in the season.  Please clarify.  Was the tree an oak?

Is this a bagworm?

I found this group under a rock each measures about 8 mm long.
I am in Fish Hoek, Cape peninsular area.
(In Zimbabwe we used to get big bagworms that made their sleeping bags out of thorns etc)

Possibly Caddisfly Pupae

Hi Brian,
We don’t know what this is, but we don’t believe they are Bagworms.  Our best guess is perhaps the Pupae of Caddisflies or Caseworms.  The larvae are aquatic and build “homes of sticks, shells or grains of sand.  Each species has a very distinctive case.  Caddisflies also spin silk.  Was this rock overhang near a stream?  If not, then we are most probably wrong.  We hope one of our readers can provide some information.  The North Carolina State University Entomology website has a nice page on Caddisflies.

Interesting – thanks for the comments!
There is no steam nearby – in fact I on a very rocky and rather dry area of sandstone hill/mountain about 2.5 km from the ocean. (Fynbos)
The drawings on the   website are similar – but I think I will have to ask the local university Zoology Dept

Then Caddisflies must be wrong.  This needs more thought.

Can you ID these bugs?

Hi We have just found this bugs, mainly the orange, ladybird looking ones on my mother’s stone fruit trees. They seem to be have suckers inbedded in the bark and the tree seems to be really struggling. She is in Adelaide, South Australia, it is currently Spring.
Thanks so much.

Lady Beetle Pupae

Hi Alison,
You have sent us photos of the pupae and a larva of some Lady Beetle.  We presume they are the same species.  They appear to be Common Spotted Ladybirds,
Harmonia conformis, based on photos posted to the Brisbane Insect website.

Lady Beetle Larva

I think it’s Ruby-Spotted Swallowtail, the same that bugguide describes as “Rare in the lower Rio Grande Valley, Texas. Has strayed as far north as Kansas.” The location is Pirituba, São Paulo, Brazil.

Ruby Spotted Swallowtail

Hi Cesar,
The range of the Ruby Spotted Swallowtail,
Papilio anchisiades, is “From south Texas south to Argentina”  according to the Butterflies and Moths of North America website, and Brazil is certainly in that range.  According to Butterfly Corner, it is also called the Red Spotted Swallowtail. 

A dozen ten lined June bugs in my basement (so far) in October!!
Location: South Eastern Idaho

We recently purchased a 100+ year old home. The home had been vacant since the spring. When we installed a new furnace and brought the home up to temperature last week 10/15/11 I noted a few days later several large bugs lying around in the basement. All were dead or nearly dead when found. I looked around and noted that in the area of the basement where the concrete floor doesn’t cover that there are some bore holes, about the size of an adult’s finger into the clay floor in this area. I was surprised to find them all dead and even more surprised once I found a picture on your website that let me guess what kind of bug it is.
Am I seeing an infestation? Are they waking and dying because we warmed up the home and they think it is spring? Will I have this happen over and over or are these beetles going to exhaust thier numbers after this false spring?

Ten Lined June Beetle

Hi Rick,
Since the larvae and pupae of the Ten Lined June Beetle live underground for several years, and since the ground temperature is a significant factor in the emergence of insects that live underground, it is likely that heating the basement triggered an early emergence for the brood of Ten Lined June Beetles you found in October.  We suspect that the clay floor might have provided a suitable location for a female to have laid eggs since the grubs feed on the roots of trees and shrubs.  We strongly doubt that the eggs were laid outside and the grubs tunneled to your basement.  We think it is more logical that at some point a female was trapped in the house and laid eggs on the floor.  We doubt that this pattern will repeat in future years, though it is entirely possible there is an isolated population of Ten Lined June Beetles that have been cyclically reproducing in the home if the required roots are near the surface of the clay floor.

Hello, I took this photo while on a slog through the Everglades (mid-October). Could you help me identify it?

Mournful Sphinx

Hi Jim,
Your somber moth,
Enyo lugubris, goes by the common name the Mournful Sphinx.  The Sphingidae of the Americas website is always a great place to identify Sphinx Moths from the family Sphingidae.  The species is found in the southernmost portions of North America as well as the tropics of Central and South America.  According to BugGuide, it is found in  “Forests, edges, presumably.”
