Your letter to the bugman:  I thought this was a cool image of a spider incapacitating a black swallowtail. This was along a trail, near the flowers the butterfly was feeding on. Maybe a crab spider? Enjoy!

Crab Spider eats Pipevine Swallowtail

Dear k. cassidy,
This is an awesome image.  We agree that this is a Crab Spider.  Crab Spiders do not build webs to snare prey.  Many species, especially pastel colored, pink, yellow or white Crab Spiders, are camouflaged in blossoms where they wait to ambush pollinating prey like bees and butterflies.  Your Swallowtail is actually a Pipevine Swallowtail.  Did you witness the Crab Spider capture the Pipevine Swallowtail?  If not, was the Swallowtail still alive when you encountered this awesome Food Chain illustration, though interestingly, this is not the first time we have received documentation of a Crab Spider eating a Pipevine Swallowtail.

yes, love the pipevine swallowtails this time of year (here they like the lilac and brodiaea best). I did not see it in the capturing phase, but this butterfly was still alive though incapacitated. Seemingly big prey, but the spider had him for sure! This is in the Auburn State Recreation Area along the American River in Northern California.
Thanks for the ink to the other crab spider catching a pipevine! I didn’t see that when I first searched.
Enjoy and share the image!

Your letter to the bugman:  Hi,
I found this spider in my house this evening.
It looks very different to other spiders that I’ve seen in the UK before and google can’t help me identify what it is.  Please can you have a look and see if you can identify it?

Crab Spider: Diaea dorsata

This is a Crab Spider and once we determined the family, it was easy to locate the identity of Diaea dorsata, which is pictured on FlickR and it is only identified to the family level on Sussex Rambler.

Your letter to the bugman:  Hi, I would love to know if this is A Grass Crab spider on my Egg Plant. And if is a dragonfly that it is eating?

Grass Crab Spider eats Flower Fly

Dear Herman,
We concur with your identification of a Grass Crab Spider in the genus
Oxytate which is pictured on Jungle Dragon where it indicates there are four species found in South Africa.  The prey is not a Dragonfly.  It is a True Fly and in our opinion, it appears to be a Flower Fly or Hover Fly in the family Syrphidae.

Your letter to the bugman:  This looks like a crab spider. Found this beauty on my kitchen counter at O-dark thirty! Startled me but then I spent a good 5 minutes trying to get an adequate picture.

Crab Spider

Dear Michelle,
This is indeed a Crab Spider in the family Thomisidae, but we are not certain of the species.  Crab Spiders are not considered dangerous to people.

Your letter to the bugman:  Hello, this lovely yellow crab spider has been hanging out on a metal picnic table all week. I’ve visited and photographed her over several days. Yesterday, she had what I at first took for a baby but now think is a suitor! He’s just a fraction of her size and his coloration is considerably different. I am not sure how he found her, as there are no flowers or yellow colored items close by. You can just see her hiding under the leaf in the 3rd photo. I did not see them interact. What do you think? Also, what are the indentations that make her abdomen look upholstered? Thanks! Love your site!

Crab Spider

Dear Crab spider fan,
Though we cannot recall reading about pheromones and Spiders, there must be some means by which a male spider is able to locate a mate.  Your images, though they do not document any actual mating activity, are still a wonderful addition to our Bug Love page.

Your letter to the bugman:  Found this bug outside my garage on a wall. Looks like a horn on the back with long antennas

Crab Spider with a horn

Dear J,
This is quite an unusual looking Spider, but we have not had any luck with its identity.  We will continue to research this matter.

Update:  Cesar Crash of Insetologia posted a comment indicating this looks like a Crab Spider in the genus Tmarus, but the FlickR posting he directed us to is not from South Africa, but rather from Portugal.  Though the submitted Spider is very delicate looking for a Crab Spider, the front two pairs of legs are considerably longer than the rear two pairs, which is a good indication the family Thomisidae is correct.
