Dear Bugger,
This is a True Bee Fly in the subfamily Bombyliinae and we found a matching image of a resting individual on the Brisbane Insect website, though it is not identified by species.  The proboscis on your specimen is definitely a match to the mouth on the image we located.

Carpenter Bee Robber Fly from South Africa

Large Unkown Fly
Location: South-Africa, Gauteng
February 4, 2012 4:40 pm
Dear Bugman,
I live in South Africa. We have a huge diversity in insects. I was in our town outside a clothing store, and there is this waste high, round steel barrier (about 3-4 inch wide) in front of it. As I waited outside the store an insect came and sat on this steel barrier… At very 1st I quickly thought it might be a bumble bee of some sort as it has quite a large size. It was black, very hairy and with 1 white stripe on its back above the wings. Upon closer inspection I realized that it was some sort of fly. I immediately took out my mobile phone and took 3 photos before it flew away. I have NEVER in my 30 years seen a fly like this and at such a huge size. Can you please tell me what it could be, as I think this might be a new species Insecta Diptera…
Thank you!

Carpenter Bee Robber Fly

Dear Eugène,
This magnificent predator is a Robber Fly in the family Asilidae.  We are not certain of the species, but it most closely resembles North American Robber Flies in the genus
Laphria, the Bee-Like Robber Flies.  On BugGuide they are described as “most species are black and yellow mimics of bumble bees or carpenter bees.”  The Bee-Like Robber Flies look similar to the Bee Killers in the genus Mallophora, but they can be distinguished by their antennae.  According to BugGuide, the Bee Killers are:  “Large, fuzzy, bee-mimicking robber flies. Resemble Laphria, another genus of robbers that mimic bumblebees, but is even hairier and has antennae with a very thin terminal final segment, whereas Laphria has thick antennae.”  Your individual has the thick antennae.  Continued research revealed that this is an entirely different genus.  We believe we have correctly identified your Carpenter Bee Robber Fly, Hyperechia marshalli, by a description on the Google Books Field Guide to Insects of South Africa where it is described as:  “Large (wingspan 34-44 mm), stout carpenter bee-mimic, uniformly black with yellow to yellowish white band of hair on hind margin of metathorax.  Legs thickly covered with long hair.  Biology: “Rests and oviposits on tree trunks.  Adults hunt from dead trunks bored by carpenter bees.  They feed on carpenter bees and other bees and wasps.  Larvae bore and live in wood tunnels in association with carpenter bee larvae, on which they are reported to feed.”  We then found a matching image on Global Species.  There is a nice photo on FlickR and another on ZipZode Zoo.

Advice on Repelling Mosquitoes needed

Cambodian missionaries being eaten by mosquitoes
January 31, 2012 11:23 pm
Hi!  My best friend and her family recently moved to Cambodia to minister and care for the street kids there (specifically children being held as sexual slaves)…apparently, word is out in the mosquito community that tasty Americans have moved in, because they (especially her children) are being eaten alive.  She said there were around 20 of them under her two year old’s mosquito net tonight.  They are, of course, using repellent, but it doesn’t seem to be helping very much.  There are holes in their house so there are LOTS of bugs everywhere.  Any ideas on a natural way to make their home comfortable?

male Asian Tiger Mosquito from our archives

Dear Heather,
Since you did not provide us with a photo to illustrate your question, we have found a photo of a male Asian Tiger Mosquito from our archives.  It should be noted that male Mosquitoes, which can be distinguished by their bushy antennae, do not bite.  The females of the species are the blood suckers.  We do not have any advice regarding repelling Mosquitoes, though there are many commercial products available.  Perhaps one of our readers will be able to provide some comments to this posting and you may be able to relay that information to the Cambodian missionaries.

Crane Flies Mating

Here are ’tipulids’ mating. I think the view of the wing venation is good enough to put it in the Phantom Crane Fly family (Ptychopteridae) as opposed to the Crane Fly family (Tipulidae). Whaddaya think?
Sorry, only one image.

Mating Crane Flies

Dear Bruce,
We are by no means experts on Crane Flies, but it is our opinion that these are not Phantom Crane Flies.  We will check with Chen Young, an expert in Crane Flies, to see if he can provide a species identification.

Hi Daniel,
The most I can tell from the images is they are crane fly species in the genus Limnophila.

Unknown Fruit Fly

Dear keyobo,
While we don’t have an actual identification, we do have an idea.  In our opinion, this is a Fruit Fly in the family Tephritidae.  We will link to the BugGuide page of North American species for comparison.  We haven’t had any luck identifying any Egyptian possibilities.  Many Fruit Flies are important agricultural pests, especially if they are introduced from exotic locations. 

Fruit Fly from Brazil

Hi, it’s me again.
As I noticed that the only photo you have of Euaresta flies is a blurry one, I’m sending this photos.
http://www.whatsthatbug.com/category/flies/fruit-flies/page/2/
It really looks like Euaresta festiva, but I observed that the wing patterns does not match 100% and I don’t think the plant where I find them is an Ambrosia trifida. I don’t see a closer species on internet.
This canadian site is a great source to identify Tephritidae.

Hi Cesar,
Thank you for sending these images of a Brazilian Fruit Fly.  We agree that your fly does resemble
Euaresta festiva as pictured on BugGuide, but the range seems to be more northern, so we doubt it is a correct species match, however, it is possibly closely related.

Large Spotted Acrea Caterpillars bothered by Tachinid Fly

Location: Kinshasa, Congo
January 2, 2012
Keith,
Thanks for the additional information on the caterpillars.  We went back yesterday to the same location where we found the Acraea zetes menippe and saw a whole lot more caterpillars.  There were quite a few climbing up a certain plant and regrouping in clumps of 5-10 individuals. We photographed a group on one of the leaves they were eating and filmed some interesting behavior.   Where the caterpillars were in a group, they seemed to react to flies.  As flies approached, they all started flailing their heads in the air.  We tried to reproduce the behavior by tapping on the leaf and blowing on the caterpillars but they only seemed to have that reaction to approaching flies.  The video can be viewed here:

A few pictures of the group on the leaf they were feeding on and one of a solitary caterpillar found nearby also attached.
Thanks again
Katy and her Dad

Keith and Daniel,
We hope you had a great New Year celebration.  We are intrigued to get your opinion on the behavior witnessed by a group of Acraea zetes caterpillars that we saw a few days ago.  We sent an email will additional photos of the caterpillars on one of their food source leaves but the internet connection has been very problematic.  Please confirm receipt or we can send again, one image at a time.   The video can be viewed here:

Thanks
Katy and Nick

Acraea Caterpillars and Tachinid Fly

Keith Wolfe responds
Katy, Dad, and Daniel,
Let’s pretend for a minute that these seven caterpillars are the five of us (mustn’t forget Mom) and two friends having a picnic, when suddenly a never-before-seen ginormous (relative to our size) fly starts buzzing around.  Bugman and I would probably be snapping photos and otherwise documenting the encounter for a scientific paper, but fast forward 1000 generations, when by now natural selection has honed our behavior to instinctively recognize these tachinid flies (http://en.wikipedia.org/wiki/Tachinidae) as mortal enemies — parasitoids whose reproductive strategy is to lay eggs inside our soft, slow-moving bodies so that their ravenous offspring will survive at our expense.  With that in mind, we too would be wildly flailing our heads, arms, and bodies, along with regurgitating bitter intestinal juices as an added deterrent.
Blue skies,
Keith

Thanks Keith,
That is great information and it explains why the caterpillars were not phased by tapping on the leaf or blowing on them but when they heard the flies nearby, they went into hyperdrive with the flailing.
Thanks again!

January 12, 2012
Dear Katy, her Dad and Keith,
Thanks so much for supplying additional photographs and a wonderful explanation of the parasitic habits of the Tachinid Flies with regards to Caterpillars.  We have been on holiday for the past week and just returned, which we hope explains our lack of input in this posting.
