I was up at 3 am, on my phone. I felt something move on my arm, and instantly this and my brand new iphone were hurling across the room onto the tile. It must have been stunned because it took it a couple minutes to move so I could find it.
I must be done sleeping for the night because I keep having random creepy crawlie sensations.
Lived in this house 14. May not be 15….

Stone Centipede

Dear sleepless in Arizona,
Though there isn’t much detail in your image, we can determine this Centipede has 15 pairs of legs, leading us to believe, based on BugGuide, that it is a Stone Centipede. We suspect it accidentally wandered into the house and had not been living there long.

Thank you.  I forgot to mention it was about an inch long.   I had taken the picture before I found your site.
Here is another picture without the flash.
Thank you for identifying it for me.

Subject: Is this really Sigmoria trimaculata?
Location: North Carolina
April 11, 2017 7:27 am
Searching around I found an older letter that had a yellow-legged black millipede in North Carolina (, but both the letter-writer’s photo and the photos on the Bug Guide page for Sigmoria trimaculata showed yellow markings on the back of the millipede as well (especially the latter!).
The millipede that I found looks completely solid black on the top/back, with only its legs and… leg-plates-joiny-bits?… being yellow. I couldn’t find any Wikipedia page about Sigmoria trimaculata to look up whether this might just be a juvenile, or a subspecies, or something like that — do you know if it is the same species? If so, why is it plain black on top?

Flatbacked Millipede

Dear S.,
We are generally very reluctant to state a Flatbacked Millipede is a definite species, but your individual looks very much like
Apheloria tigana which is pictured on BugGuide where it states:  “‘Apheloria tigana is the dominant xystodesmid millipede in central North Carolina, particularly the “Triangle” (Raleigh, Durham, Chapel Hill region). Individuals typically have yellow paranota (lateral segmental expansions on the dorsa), a yellow middorsal spot on the anterior margin of the collum or 1st segment, and yellow middorsal spots on the caudalmost 3-5 segments. In central NC south of the Deep/Cape Fear Rivers there is a different and undescribed species with yellow middorsal splotches on essentially every segment.’ – Roland Shelley, North Carolina State Museum of Natural Sciences.”

Hi Daniel,
Thank you for the response and the link! I guess they are the sort of
creature where species identification is generally rather tricky? But
that does look exactly like my fella — much appreciated 🙂

April 14, 2017
(So in the last two days, I’ve been seeing quite a few of these
critters curled up on the sidewalk in the harsh daylight where I’ve
never seen ’em before, seemingly unable to move even when I nudge them
to a grassy area — not at all like the briskly ambulating specimen
that originally caught my eye. It’s a little worrying. The internet
says millipedes might migrate in spring and fall, but it’s pretty much
already summer hereabouts, and my searches keep coming up 90% about
millipede extermination… sigh…)

Alas, that is because there are far more people want to eliminate lower beasts from their lives than those who want to learn about them.

Hi Bugman,
My son was bitten by a spider the other day on his elbow. We checked his room and we couldn’t find anything but were quite alarmed because we have allot of black widow and brown widow spiders in our garden.
The symptoms were not severe included fever, stomach ache, swollen bite site and headache, as well as muscle ache.
We then while cleaning found a little critter which we know to be a scorpion spider which I think gave him a nip.
I have attached pictures of bite so people can see and also spider that we caught. The site initially looked like 4 tiny mosquito bites but pain he experience was something else.
Hope this helps others.
We live in Pineslopes, Fourways, Gauteng.

Scorpion Spider

Dear Tenielle,
Thanks for your submission.  We have had many requests for information about the Scorpion Spider, and we have not had any luck locating any information online regarding the effects of such a bite.  While we appreciate your submission, we have to say that your evidence that the bite actually came from a Scorpion Spider is circumstantial.  We would hate to think that if the police were summoned to a robbery, that the first person they found near the sight of the robbery would be assumed to be guilty.  We are not implying that the Scorpion Spider did not bite your son, but rather that we cannot be certain if the Scorpion Spider bit your son.  The reaction you describe, including the fever and aches, sounds like the description of a Black Widow bite.  According to Web MD, though we should qualify that this is the North American Black Widow and not members of the genus from Africa:

“In most cases of a black widow spider bite, symptoms consist only of:

  • Minimal to sharp pain followed by swelling and redness at the site of the bite.
  • One or two small fang marks like tiny red spots.

In some cases, severe symptoms appear within 30 to 60 minutes. These include:

  • Muscle cramps and spasms that start near the bite and then spread and increase in severity for 6 to 12 hours.
  • Chills, fever, nausea, or vomiting.
  • Sweating.
  • Severe belly, back, or chest pain.
  • Headache.
  • Stupor, restlessness, or shock.
  • Severe high blood pressure.”

Bite, possibly from a Scorpion Spider

We are not in the habit of giving parenting advice, but you might want to seek medical attention.

Vine Hawkmoth Caterpillar

Dear Stuart,
This is a Vine Hawkmoth Caterpillar,
Hippotion celerio.  We just posted a green individual this morning.  According to Butterfly House:  “This Caterpillar occurs world-wide. It can occur in several different colour forms: green, brown, red or dark grey. It usually has an eyespot each side of the first and second abdominal segments, those on the first segment being larger.”

Can you please help me identify the bug below – shot in India?

Blister Beetle

Dear John,
This is a Blister Beetle in the family Meloidae.  Though the markings are not exactly the same, it might be a color variation or a different species in the same genus as this unidentified Blister Beetle on India BioDiversity.  We believe it is in the genus
Mylabris based on images we have located online, including on Bold Systems Taxonomy.  Blister Beetles should be handled with extreme caution as they secrete a compound known as cantharidin that is known to cause blistering in human skin.

Hi Daniel
Thanks so much…I almost labelled it as a blister beetle…but as you say the markings are somewhat different.
Must also be a cousin of the Cantharides Beetle we used to get in Africa – which caused extreme blistering!
Thanks again and for such a quick reponse.

My Aunt found this fella on her lemon tree and there is debate as to whether it’s an Elephant Hawk Caterpillar or an Orange Dog. Please, help to clarify, she didn’t check to see if it had the scented appendages that an orange dog would display while threatened, unfortunately. Thank you for what you do!!

Orange Dog

Dear Artist Formally Known as Starving,
This is definitely an Orange Dog, the larva of a Giant Swallowtail.  The Elephant Hawkmoth is NOT a North American species.  Interestingly, though its native range is Eastern North America, most of our Giant Swallowtail sightings now come from Southern California as the butterfly’s range has increased due to the cultivation of citrus.  The species has adapted to feeding on the leaves of citrus, which is not native to North America, but it now seems to be a preferred host plant.  We believe Giant Swallowtails were first reported in Los Angeles in the late 1990s, and now they are quite common (t)here.  According to the Los Angeles Times in 2007:  “The giant swallowtail butterfly,
Heraclides (Papilio) cresphontes, is native to the Southeast. Since the 1960s, populations have spread west following a corridor of suburban development and the species’ favorite larval food source — citrus — through Arizona, into the Imperial Valley, then San Diego and north to Orange and Los Angeles counties. They’ve been sighted as far north as Santa Barbara and Bakersfield.  Numbers have surged since 2000, says Jess Morton, president of the Palos Verdes-South Bay chapter of the Audubon Society. Members have held a butterfly count at the same location, on the first Sunday in July, every year since 1991. According to their records, a single giant swallowtail was first seen in the South Bay in 2000. They counted 23 in 2007.”

THANK YOU SO MUCH. You broke it down for us and everything!
