Your letter to the bugman:  Dear Bugman,
Are these bees or wasps? where feeding on bottle brush. They where not small, much bigger than paper wasp, but they looked much more wasp like than a bee.
Malaga province,  Spain,  October 22, 2018
Thanks in advance

Unknown Wasp

Dear Perry,
This is definitely a Wasp and not a Bee.  It looks to us like one of the Paper Wasps in the genus
Polistes, but we have not found any images from Spain on the internet that resemble your individual.  Perhaps one of our readers will be able to substantiate or provide a correction.

Geographic location of the bug:  Andover, NJ
Your letter to the bugman:  I found a couple of these big wasps feeding on my mountain mint this morning and my first thought was “eastern yellow jacket”.  But as I looked closer, they don’t quite look right for the easter yj’s.  Any thoughts?  There were only two and they were very happy to nectar in among the bees and mason wasps.  No signs of aggression.

Possibly Common Aerial Yellowjacket

Hi Deborah,
After the last time we misidentified your Parasitic Yellowjacket, we demonstrated that we don’t really have much in the way of entomological chops.  According to BugGuide, in the subfamily Vespinae which contains Yellowjackets and Hornets, there are “22 spp. (of which 4 adventive or 2?) in 3 genera in our fauna” and many look remarkably similar.  This individual looks to us like it might be the Aerial Yellowjacket,
Dolichovespula arenaria, which is pictured on BugGuide, but it is not represented on Insect Identification for the Casual Observer using the New Jersey Hymenopteran filter.  Of the Common Aerial Yellowjacket, BugGuide states:  “They have mostly aerial nests, from a few centimeters above ground to the tops or trees, or houses or sheds. But in some cases they build nests under rocks or even underground.”  Does that look correct to you?  We can’t say for certain.

Possibly Common Aerial Yellowjacket

Hi Daniel,
I had actually wondered if it might be The Common Aerial YJ, but I just wasn’t sure.  I’m inclined to agree that this seems the most likely id for this big wasp.  Interesting, though, that Bugguide describes them as being primarily predatory and these were definitely after nectar, totally ignoring the many other tasty insects on the mint.
The mountain mint has yielded a couple of interesting feather-legged flies this morning so I’m going to take a crack at id-ing them, but may be back for an assist on one.  I also saw, for the briefest of moments  Great Black Wasp, which was thrilling.  She buzzed me a few times before taking off.  I don’t see them all that often here, so that was pretty exciting.
Best
Debbi

Your letter to the bugman:  Have seen quite a few of these on holiday in Italy. This particular one is in the ruins of Pompeii but many were not. Could you attempt to identify I’d be interested to know what it is

Oriental Hornet

Dear George,
When we searched for Hornet sightings in Pompeii, we found this FlickR posting of an Oriental Hornet,
Vespa orientalis.  According to Encyclopedia of Life, the Oriental Hornet:  “is a social insect of the Vespidae family. It can be found in Southwest Asia, Northeast Africa, the island of Madagascar, and parts of Southern Europe. Oriental hornets have also been found in a few isolated locations such as Mexico due to human introduction. The Oriental hornet lives in seasonal colonies consisting of caste system dominated by a queen. The hornet builds its nests underground and communicates using sound vibrations. The hornet has a yellow stripe on its cuticle (exoskeleton) which can absorb sunlight to generate a small electrical potential, and it has been suggested that this might help supply energy for digging. The adult hornet eats nectar and fruits and scavenges for insects and animal proteins to feed to their young. Because they are scavengers, the hornets may also serve as a transmitter of disease following consumption infected plants. The hornets are a primary pest to honey bees, attacking bee colonies to obtain honey and animal proteins. The sting of an Oriental hornet can be quite painful to humans and some humans are allergic to stings.

Subject:  Bald-faced Hornet or Blackjacket?

Your letter to the bugman:  I found this robust looking hornet at the edge of the woods on our property a couple of days ago.  It doesn’t look quite right for a bald-faced hornet to me, although several have insisted that it is one.  I think it looks better for a Blackjacket, which would also be a new species for me.
Can you give me some wisdom?

Parasitic Yellowjacket

Dear Deborah,
We always enjoy your submissions.  Quite frankly, we do not know how to easily tell the difference between a Bald Faced Hornet and a Blackjacket, but we are working on getting you an answer.  Our gut instinct is that this is a Bald Faced Hornet.  We have contacted Eric Eaton for assistance.

Parasitic Yellowjacket

Eric Eaton Responds
Daniel:
Oh, wow, this is neither Bald-faced Hornet nor Blackjacket.  It is a social parasite of the Aerial Yellowjacket.  It is called the Parasitic Yellowjacket, Dolichovespula arctica.  Always a great find!  They are not that common.

Eric
author, Kaufman Field Guide to Insects of North America

Hi again Deborah,
BugGuide also indicates:  “The species most easily confused with the Parasitic is the Blackjacket.”  Eric Eaton’s blog posting is very informative, including the statement that the Parasitic Yellowjacket “has no worker caste like the Aerial Yellowjacket, only reproductive females, and males.”

Well, how cool!!  I am so glad I sent this to you.  I just didn’t think it was a bald-faced, but would never have come up with this identification without your and Eric’s help.  Thank you!

Your letter to the bugman:  Woke up to find this giant bee IN MY BEDROOM this morning. It wanted out (and I wanted it out) and somehow everyone left the room alive. It was a significantly large bee — unquestionably the biggest I’ve ever seen, and solidly in the inch-long realm.

European Hornet

This is not a bee.  It is a European Hornet, a species introduced to North America at the end of the nineteenth century.

Your letter to the bugman —
This bee was found in my garage. I’ve never seen one so big. Unfortunately it was killed before I could get to it. The picture doesn’t do it justice. It’s about the thickness of a pinky finger. The giant Asian hornet is the only thing I could find that looked similar. Should I be worried?

European Hornet

Dear Oswald,
This is a European Hornet, a species introduced to North America toward the end of the Nineteenth Century.  It has naturalized.  Though European Hornets are not aggressive, they will sting to defend a nest.
