What’s This Bug?

My friend found this in his home and I tried to identify it for him, but nothing similar is in my insect guide. Any idea?

Flat Red Bark Beetle

Hi Derek,
It is a flat, red beetle and it has the common name Flat Red Bark Beetle,
Cucujus clavipes, because, according to BugGuide, it is:  “Found under the bark of ash and poplar, especially recently felled trees” where it is “presumably predaceous on other arthropods.

Spider Trapping a Baby Black Widow
Location: Southern California
November 4, 2010 1:10 pm
We found this spider in our backyard on the patio trapping a baby black widow. We are thinking it is either a male black widow or a brown widow, but are uncertain. We live in Southern California in the Murrieta/Temecula area. We would love to find out what it is. Thanks!

Black Widow Cannibalism

Hi Courtney,
We are intrigued with your photos of Black Widow cannibalism.  The predator in this photo is an immature female Black Widow that will eventually lose that striped pattern and become a glossy black spider, and the prey is exhibiting the telltale red hourglass of a Black Widow as well.

Black Widow Cannibalism

Thank you so much.  Is Black Widow cannibalism common?  Do all females change like this?  Would it have started out all black like the baby here? I understand if you can’t answer all my questions, but I thought I’d try.

Hi Courtney,
We were going to paste the third of your photos into this response so we could better determine the identity of the victim.  We have never seen data on the frequency of Black Widow cannibalism, but the name and alleged reason may be an indication that there is fact in the lore.  With that said, this may be a virgin adolescent female who is still wearing her prepubescent markings.  That may be a suitor that sacrificed his life for the perpetuation of the species.  Black Widows may be able to mate as adolescents and then storing the spermatozoa until it is needed.  Adult females are glossy black and we have not seen documentation of mature females marked otherwise.

A chameleon lynx spider?
Location: South Pasadena, CA
November 4, 2010 11:15 pm
I’m sending two pictures, which were taken six days apart. I’m nearly certain it’s the same spider. Apparently a lynx spider, though not all that green. It seems to have changed color to conceal itself. It also seems to be displaying a nice pink peace sign, although it’s quite a killer.

Green Lynx eats Honey Bee

Hi Barbara,
Judging by the size of your Green Lynx Spider, she is getting ready to lay eggs.  Your second photo shows a tangle of silk that she will probably use as a nesting site if she is not disturbed.  She will remain in the vicinity of the egg sac guarding it and the emerging spiderlings if she lives that long.  There is variation in the coloration of Green Lynx Spiders and your pink individual is most attractive.  BugGuide has a posting of a similar pink female and there is discussion about a comment by Lynette Schimming that older females sometimes turn red.  When she lays eggs, we hope you will send us some additional photos.

Odd Striped Ant
Location: Upstate NY

I found this little ant-like creature crawling up the inside of my pants. Felt like it might have bit me but it could have just been his/her jagged legs.
Any idea on what this insect is?

Checkered Beetle

Hi Jillian,
You have had a close encounter with a Checkered Beetle in the family Cleridae, and it appears as though it is
Thanasimus dubius according to images posted to BugGuide.  The family page on BugGuide offers this information:  “predaceous on other insects, larvae mostly on wood- and cone-borers; some adults feed on pollen; a few species are scavengers.

Mothzilla in Venezuela
Location: Venezuela
November 4, 2010 11:31 pm
My brother sent this picture of a large moth on his window sill in Venezuela. We did some searches but could not find a similar similar one with a description. The key in the picture is a standard size which puts this one at about ~6 inches or so? He called it Mothzilla! But looking for a true identity.
Yes, you can use the image.

White Witch

Dear Two brothers,
This is quite exciting.  This is only the second image we have received of a White Witch, the moth with the largest wingspan in the world.  The largest specimens are 12 inches across.  The first image of a White Witch arrived last year and it was from Trinidad.

Tanzanian 10 legged spider with claws
November 4, 2010 3:15 am
Dear Bugman,
I am living in a tropical coastal region of north Tanzania, there are all sorts of interesting bugs here (wadudu in Swahili!) but I thought this one was especially good and was wondering if you could help me identify it. It seems to have 10 legs; the front two with hooks or claws and the next row back being much longer and thinner. Probably about 10cm leg span. I thought it might be a Solifugae of some kind but haven’t found anything online which looks similar.
Looking forward to your thoughts,

Hi Olly,
This is a Tailless Whipscorpion in the order Amblypygi, and despite its name, it is perfectly harmless since it does not have venom.  They are shy nocturnal hunters.  BugGuide describes them as:  “Spiderlike Large pincer-like, powerful and spiny claws used for capturing prey Wide head and thorax Flattenned overall appearance No spinnerets First pair of legs are very long and whiplike and function like antennae Eight eyes.
