This wasp was very busy getting nectar from the flowers on my dads tree, so I managed to get a few shots of it. I don’t know what kind of wasp it is, whether it’s dangerous or not. Either way, I left it alone after getting the photos.

Dear Rebecca,
This is a Paper Wasp in the genus
Polistes, but we are not certain of the species.  We suspect that Paper Wasps in Taiwan behave much like Paper Wasps in other parts of the world.  Some species are more aggressive than others, but solitary individuals gathering nectar do not pose much of a threat to humans.  Paper Wasps are social wasps that build a nest, and they will defend a nest against a potential threat, so we would strongly urge people not to disturb the nest of a Paper Wasp.  According to BugGuide, which deals with North American species:  “Semi-social wasps. Unlike social (eusocial) wasps, where workers are sterile females, in Polistes all females are potential breeders. (See comments below for details.) Fertilized queens overwinter in crevices or under bark. In spring they build a nest and the colony builds up over the summer. At first, only workers (sterile females) are produced. Mature colonies have up to 30 adults. A young queen is the sole survivor of the colony. (I am presuming this queen disperses to find an unrelated male on flowers in the fall.)”  BugGuide also notes:  “Not as aggressive as Hornets, Yellowjackets. May be considered beneficial to gardeners because of predation on herbivorous insects.

We’re looking for a confirmation on this being a robber fly. Your site was soo helpful in both researching what we saw out our front door and learning more about the bug in question.
This guy was about 3 cm in length and “snacking” on a wasp.
Our 3 and 5 yr old were fighting for the best position to watch this guy through a window. Question – how bad would a bite from this guy be to a small kid? And, is it okay to hang out around them as they protect our air space?

Red Footed Cannibalfly eats Paper Wasp

Hi Jeff,
We agree that this is a Red Footed Cannibalfly, and it appears to be eating a Paper Wasp in the genus
Polistes (See BugGuide).  We believe a bite from a Red Footed Cannibalfly would be painful, but otherwise present no lasting effects, however we should qualify that that we believe the chances of being bitten are at about 0% unless a person decided to try to catch a Red Footed Cannibalfly by hand.  They are not aggressive towards humans, and if provoked, they would most likely just fly off.  Handling them is a totally different matter.

Does this thing bite or sting humans?

Dear freaked out,
Though the Red-Footed Cannibalfly,
Promachus rufipes, is a very adept hunter capable of taking stinging wasps like this Paper Wasp on the wing, they are not aggressive towards humans.  With that said, if a human ever tried to capture a Red-Footed Cannibalfly or other large Robber Fly with bare hands, a bite may result.

We went on a little hike in a nearby wetlands area and along our way we found two interesting bugs. One of them looks like a kind of wasp to me, the other one is completely new to me! I’m curious what they are, especially the one with the long stinger for a nose? Thanks for helping out!

Dear Joyce,
We have already written back that you submitted images of a Bee Fly and a Paper Wasp.  We are posting your image of the Paper Wasp in the genus
Polistes.  It appears it might be chewing on that weathered wood to make paper pulp for the construction of its nest.  Paper Wasps make nests of chewed wood pulp, creating chambers for raising young.  The nest has a queen and the colony survives for a single season.  Based on its coloring and markings and its resemblance to this image on BugGuide, this might be a Northern Paper Waps, Polistes fuscatus, which despite its common name, ranges as far south as Florida.

I was trying to get some shots of this paper wasp when I realized that it (she?) was eating or carrying something. I wasn’t able to get enough magnification in the image to determine what was in the wasps mouth, although it does look a little like a grub. The wasp eventually got tired of me taking pictures and took off with whatever it was still in its jaws. I’d be very interested in what was going on here.
Thank you!

Paper Wasp with Prey

Paper Wasp with Prey

Hi Deborah,
It would be very difficult to identify the prey in your images conclusively, however, we can make an educated guess.  Paper Wasps in the genus
Polistes take nectar for nourishment, however, the workers do capture insects to feed to the developing larvae in the nest.  Caterpillars are a favored prey of Paper Wasps, and when they are captured, the caterpillars are often skinned and rolled into a ball for easy transportation back to the nest.  We feel strongly that the prey in your images is a Caterpillar.

Thank you!  What a fascinating thing to observe.  I thought it might be too early for them to be feeding larvae, but I guess it’s not.  Very cool.

I found a couple of wasps nests around an old building and noticed two types of wasps. One type looked normal but the other type had very long wings. What type of Wasp is this

Hi Lanhill,
These are Paper Wasps in the genus Polistes.  They are not considered dangerous, though we have been getting numerous reports of aggressive Red Wasps recently.
