This wasp? was rather aggressive.

Mammoth Wasp

This is a Mammoth Wasp in the family Scoliidae, and though there are several images posted to iSpot of this distinctive Scoliid, it is only identified to the family level.  Female Mammoth Wasps prey upon the grubs of Scarab Beetles which provide food for her developing young.

Hey, NSW Australia here. Just found this guy near the door. He is larger than a wasp and smaller than a hornet also has the iridescent type blue wings. Just wondering what he might be… haven’t seen this one before

Black Flower Wasp

Dear Andrew,
Though we first located this image on FlickR, we are much more comfortable informing you that this is a Black Flower Wasp,
Austroscolia soror, since the same image is posted to iNaturalist.  The species is also pictured on the Atlas of Living Australia and Encyclopedia of Life.  The Black Flower Wasp is a member of the family Scoliidae, and females withing the family prey on the grubs of Scarab Beetles by laying their eggs, so the beetle grubs provide a live food source for the developing wasp larvae.

Dear Daniel Marlos:
Just happened upon your site and decided to let you know about my own minor efforts in entomology. I spend a good deal of my time (retired) in Morocco and one thing I do is take photos of all sorts of subjects, including plenty of ‘bug’ pictures – especially bees and butterflies. Many are as yet to be uploaded since I’m trying to learn the basics about taxonomy but, alas, it’s slow going!
… Thanks for any help or suggestions you might offer.

Scarab Hunter Wasp, we believe

Scarab Hunter Wasp, we believe

Dear Jearld,
WE believe the hairy Hymenopteran is a Scarab Hunter Wasp in the family Scoliidae.  Here is an image that looks similar that is posted to PicClick, but we can’t find any information on the species.  Though the colors are quite different, the body morphology of this
Scolia dubia posted to BugGuide looks similar to that of your individual.  Your other wasp might be a Paper Wasp in the subfamily Polistinae.

Subject: Ant or Wasp?

Hi,
I took this picture in Kitchen Garden, Pasir Ris Park of Singapore on a fine October morning. I can’t figure out whether this is an ant or a wasp. Help appreciated. Thanks!

Mammoth Wasp: Scolia species

Mammoth Wasp: Scolia species

Dear Teng,
Your image of a Mammoth Wasp (AKA Flower Wasp or Scarab Hunter) in the family Scoliidae is gorgeous.  It looks very similar to this FlickR image from Indonesia of
Scolia vollenhoveni, and we suspect it is either the same species or a closely related species in the same genus.  Of the North American species, BugGuide notes:  “Larvae are parasitoids of ground-dwelling scarab grubs, esp. Phyllophaga; adults take nectar.”   Of the genus, BugGuide notes:  “7 spp. in our area, a great many more in the Old World (30 in Europe alone).”

Dear Daniel,
Thanks a million!
Regards,
Teng

Just as we were leaving the office today to gawk at the guerilla art Donald Trump sculpture at Wacko (see LA Times or LAist ), we had to make a slight delay to take some images of this gorgeous female Scarab Hunter Wasp,
Campsomeris tolteca, nectaring on the flowering peppermint.  We first identified this species four years ago in Elyria Canyon Park.  Alas, the statue was in for the night, so we will have to return to Wacko during business hours.   Our identification of the female Scarab Hunter Wasp can be verified on BugGuide.

Subject: Walking in Florida Pine Woods
Location: Near US 1 and Old Kings Road

Hi,
I took a photo of this insect on a trail in Flagler County Florida yesterday, Aug 7, late in the day. The location was pine uplands at Hewitt Sawmill historic site. It was longer than an inch, had purplish long wings, made no sound at that time, black long body but not thin, and it had two yellow spots on each side of its abdomen. Its face looks like a giant ant. It was walking slowly across the shell-sand trail. The closest I found online is the Eastern Sawfly, but the markings don’t exactly match up. Could you pinpoint its identity?
thanks!

Scarab Hunter Wasp

Scarab Hunter Wasp

Dear Tom,
This is a Scarab Hunter Wasp, a name that applies to the entire genus
Campsomeris, and your individual is Campsomeris quadrimaculata with the species name of the binomial a reference to the four spots you observed.  You can verify our ID on BugGuide.  According to the genus page on BugGuide:  “According to Nick Fensler: The females Campsomeris as well as other members of the Campsomerinae use white grubs (Scarabaeidae) as food for their young. Unlike sphecids, eumenines, and pompilids these wasps do not appear to have any type of prey transportation and dig to the ground-dwelling beetle larvae, sting it to paralyze it, and then lay an egg. They may dig around the grub to form a small cell. Since they use this nesting strategy they are often seen flying low to the ground (searching) in a figure eight pattern (but the flight pattern gets more erratic when they ‘smell’ something). The adults use nectar as a food source and are common on flowers.”

Way cool!  Thank you.  I hope to see more of these out on my walks (and stay out of their way!), but if I’m with anyone I can now ID it thanks to whatsthatbug!  Best, Tom
