My wife captured this shot in our front garden. I wonder if the wasp removed the huntsman spiders legs for transport purposes?

Spider Wasp and Huntsman Prey

Spider Wasp and Huntsman Prey

We get several very dramatic submissions from Australia each year of Spider Wasps in the family Pompilidae with Huntsman Spider prey.  The female Spider Wasps stings and paralyzes the Huntsman Spider and then drags it back to her burrow where she lays an egg on the paralyzed Spider.  When the egg hatches, the wasp larva feeds on the living but paralyzed Spider.  It appears that your Spider Wasp has removed the legs of the Huntsman Spider by biting them off in order to make transportation easier.  Based on images posted to the Brisbane Insect site, we believe your Spider Wasp is in the genus Fabriogenia.

Working in California Valley and have seen a few of these insects slowly crawling around. There are flies everywhere, tons of them, but just today caught a slow mover munching on one of the flies, hence becoming a welcome addition to my home. They’ve been doing well too as they’ve left a pile of leftover carcasses at the base of their attack.
Just wondering what it is.
Thanks,

Assassin Bug eats Flesh Fly

Leafhopper Assassin Bug eats Flesh Fly

Dear Chris,
The predator is an Assassin Bug in the genus
Zelus, and the prey appears to be a Flesh Fly.  We believe the Assassin is a Leafhopper Assassin Bug, Zelus renardii, based on this BugGuide image.  According to BugGuide:  “Generalist predator (despite its common name suggesting host specificity).”  Zelus Assassin Bugs seem to bite humans more readily than most other Assassin Bugs, with the exception of blood-sucking Kissing Bugs, and though their bite is not considered dangerous to humans, it may leave the bite site tender and swollen.  They should be handled with caution to avoid bites.

Every year, these caterpillars came and use to stay in different species of trees. The most commum tree is the Prunus selowii. They use to stay in a big group , normally .8 m to 1,0 abovo the ground. They are very predate by hemiptera insesct, as you can see in the picture.
Totally inofensive, I means, they don´t provoque any irritation in the skin when manipulate.

Possibly Morpho Caterpillars

Giant Silkmoth Caterpillars

Dear Wilsonpni,
Though your caterpillars resemble the caterpillar of a Black Witch,
Ascalapha odorata, based on this BugGuide image, we do not believe that is a correct identification.  We are pretty certain Black Witch Caterpillars do not feed in such aggregations.  Though the color is different, your caterpillars remind us of Morpho Caterpillars from our archives.  We will contact Keith Wolfe to get his opinion.  The image of the Predatory Stink Bug nymph feeding on a Caterpillar is a nice addition to our Food Chain tag.

Olá Daniel,
Nope, sorry, these are moth caterpillars, those of Morpho appearing distinctly different.
Abraços,
Keith

Thanks to a comment from contributor Cesar Crash of Insetologia, we now believe these are Giant Silkmoth Caterpillars from the genus
Arsenura.

Assassin Bug nymph eats Fly

Assassin Bug nymph eats Fly

Dear Patty,
This is an Assassin Bug nymph in the genus
Zelus.  Though they are not aggressive towards humans, they can deliver a painful bite if carelessly handled.  Their mouths are adapted to piercing the exoskeleton and sucking the fluids from prey.  You can try capturing this Assassin Bug nymph in an overturned glass and transporting it back outside.  We will be post-dating your submission to go live to our site while we are away from the office at the end of the week.

thank you so much for the info. I’d kinda like to put him in an insect habitat….. seems everything i’ve been reading… they live 1-2 years in captivity… do you know if that is correct?
I have a couple of lady bugs in with him (DUG) right now… but he doesn’t seem interested. I’m thinking they might be too big for him? No?… i gave him a small spider yesterday… and he skawfed it RIGHT UP!!!! will he eat small crickets and meal worms?

Since Assassin Bugs are predators, we would expect them to eat any insects that move.  Perhaps the Lady Bugs are foul tasting.

thank you…. I bought him(DUG) a new home today….. complete with baby crickets and tiny meal worms…….. hope to see him eating soon! How long do you think he’ll live in the right conditions? He fascinates me… and made his appearance in my life at a very chaotic time, definitely something to keep my mind occupied…
Thanks again.

Perhaps a year in captivity.

Subject: Banded Garden Spider?

I *think* this is a female Banded Garden Spider. I first saw it on August 14 and at first thought it was a tree snail due to the appearance of the back. The body was more than an inch long, and it stayed in its web in the same place for weeks, catching bees. I was rather hoping there would be a lot of baby spiders later, but a few weeks later there were 2 days of torrential rain during which time I didn’t look for her & when I did look, she was gone, leaving an intact web and no clue as to her disappearance. The third photo was one of a lucky series- I was taking a picture of her holding a webbed up bee when another bee landed in the web. She was on that second bee so fast I had to scramble to get pics! (I’ll send 3 more of the series in another query.)Spider webbing up caught bee. I chose these out of the series because one shows the bee clearly, and the other two do a fair job of showing the spinnerets in action.

Dear Curious in Florida,
Thanks for sending in your wonderful images of a Banded Garden Spider or Banded Orbweaver,
Argiope trifasciata.  They are an excellent addition to our archives.

Saw this the other day and at first thought the spider had the bug, until the bug ran off in circles for a second and then went back and started dragging the spider to a small hole in the sand. He then started to bury the spider. I actually have video, so these are stills. Just wondering what it is and whether or not it is a danger to any pets (assuming you don’t have pet spiders).

Hi Ginger,
We believe your Spider Wasp is
Tachypompilus ferrugineus based on images and range information on BugGuide.  Of the genus, BugGuide notes:  “Adults are often found taking nectar from flowers (Daucus, Pastinaca, and Eryngium). Females provision nests mainly with Lycosids.”
