Saw it in our garden during Desember 2016 in Brackenfell, Western Cape. Have never seen it before and I have been living here many years. Are they found all over South Africa?

Carpenter Bee Robber Fly eats Paper Wasp

Dear Jackie,
This Carpenter Bee Robber Fly,
Hyperechia marshalli, feeding on what appears to be a Paper Wasp is a marvelous addition to our Food Chain page.  We are not certain of the exact extent of its range in South Africa, but in our own archives, we have gotten reports from Johannesburg and Gauteng as well as Tanzania.

Carpenter Bee Robber Fly eats Wasp

Dear Gerrit,
This is definitely a Carpenter Bee Robber Fly,
Hyperechia marshalli, a species represented on our site in several previous postings.  We verified its identity on iSpot.  These impressive aerial predators have a particular fondness for preying on large, stinging insects.  Your individual appears to be eating a Paper Wasp.  The Carpenter Bee Robber Fly is also pictured on iNaturalist.

I found this giant fly on a window, feet caught in spiderwebbing, 25km south of Manjimup. It is 45mm from head to tip of abdomen, is bright orange on the top of the abdomen and black and hairy underneath. It has tufts of black and white hairs down the sides of the abdomen and very strong black legs covered in barbs.

Giant Yellow Robber Fly

Dear PK,
The Giant Yellow Robber Fly,
Blepharotes coriarius, is one of the most impressive looking flies we have ever received for posting.  We were quite amazed the first time we posted an image of a Giant Yellow Robber Fly nine years ago.  It is one impressive predator.

I keep seeing this weird dinosaure like bug around.
It has a long skinny curved body, unless it’s a sting (I know nothing about insects), and 6 legs.
We never see it flying but, often completely still. Also it’s very big, and tall on its legs.
let me know what you think 🙂

Robber Fly

Dear Sacha,
This is a predatory Robber Fly in the family Asilidae, and though there is not much detail in your image, it does resemble this individual posted to iSpot.  While we would not rule out the possibility of a person being bitten by a Robber Fly, we think that is highly unlikely unless a person tried to handle a Robber Fly.  Predatory Robber Flies generally prey upon flying insects that they catch on the wing.

I found this bug in Orlando, Florida in the fall. It seemed to be hairy and was mostly black with small touches of yellow on its body. It had large wings.

Southern Bee Killer

Southern Bee Killer

Dear Meg,
We feel confident, because of its markings, that your Robber Fly is a Southern Bee Killer,
Mallophora orcina.  This large predator takes large prey, including bees and wasps, by catching them on the wing.
