Hedgehog Fly / Dejeania bombylans

Gotha! Ha-Ha! Did you really think a porcupine fly existed? Looking at this fly with its spiky bristles, you can easily see why I choose to call it "Porcupine Fly". Actually it is called a "Hedgehog Fly". Please also see the image in the workshop.

I don't think I'm wrong when I say that most of us probably dislike flies, for very obvious reasons, and as I mentioned in my previous notes with the "Tormentor/Flesh fly" and "Is a fly just a fly/Blow fly" postings in my gallery, I always thought a fly is just a fly. (Loot says, "A dead fly is the best fly".) However, that was before I started taking photos myself. Soon I changed my mind as I discovered that there is much more to a fly than meets the casual eye. I am sure you will agree with me on that statement, when looking at this fly with its very distinct features.

As far as I know this is only the 2nd time this fly features on Trek Nature. The 1st time it was posted by Gerhard Theron (gerhardt) in November 2004.

Photography has changed my life completely. I don't think even while being at school, I found Biology as interesting as I find it now-a-days. I find the most interesting creatures in the garden. Sometimes the features of these tiny animals are absolutely amusing, sometimes strange and sometimes even mind boggling, and one wonder how they live in that teeny, weenie bodies. That is when the interesting part starts as to when you have to read up and research to find the answers.

As with the previous two fly postings which I've mentioned, it was quite difficult to obtain sufficient and worthwhile information about these insects. I have taken the following information from one or two snippets from the Internet and used a small extract from the Field Guide to Insects of Southern Africa - by Picker, Griffiths and Weaving - Struik Publishers. The order Diptera have been described plenty of times on the site and an abundance of information is available. I therefore am not going to repeat all that have already been said just for the sake of it.

I still have a variety of wonderful and most colourful fly photos in the archives, which I still plan to share in due course.


Short General Overview
Tachinid flies, of which the Dejeania bombylans is a part off, belong to the family Tachinidae.

They are medium sized flies, often covered with strong bristles. Recognised under magnification by extra ridge (post-scutellum) under the most backward-projecting part of the thorax (scutellum). Adults feed on nectar, and often have a characteristic buzzing flight. All species are internal parasites of insects, or occasionally, centipedes. Larvae feed first on non-essential organs of the host and attack vital organs only when they are just about to pupate.

Butterflies and moths are the most common hosts, but any large larva from a range of groups, including bugs, grasshoppers, beetles and (rarely) wasps and bees, is attacked. Although there is a fair degree of host-specificity at the taxonomic level of order, there is little or none at the species level. Females may lay eggs directly into the host or on a plant that the host may eat inadvertently; alternatively, eggs may hatch into larvae that find their way into the host. Tachinids are important agriculturally as they suppress populations of injurious moth caterpillars. There are about 377 species known from the region.

This specific specie is known to parasitise only the African Boll Worm (Helicoverpa armigera).

I hope you enjoyed looking at this photo as much as I took pleasure in taking it. Normally I'm not one to brag very easily. I still have so much to learn about photography, but I do want to mention the following. An entomologist friend from the Cape will forward this specific image together with the workshop photo and the photos of the Hose Nose Cycad weevil to one of the authors of the above-mentioned book, Dr. Mike Picker. We (Loot & I) are of the opinion that these photos are more informative and of a higher quality than anything else we could find of these specific species on the Internet or in the book.

Hello Anna,
This is a super sharp macro of this Hedgehog Fly, taken from an excellent fronto-dorsal POV that shows all the features of this tachinid fly, including the 'spines'. The plain leaf BG are addinitioal aspects that make this macro top class.
Well done and thanks for sharing this one,
Best regards,
Ivan

Hello Anna,
Good to see this unique insect with protective spiky armour. I do agree with you that new generation photography has changed our lives. All of sudden we have started enjoying our surroundings & thanks to the internet, so that tremendous amount of information is available just with a click of mouse! Very well shot specimen of fly with perfect luminosity, details & sharpness. Thanks for sharing this macro photograph.

Hi Anna.
Absolutely fantastic image with unbelievable details and sharpness. Lights and shadows, colours and sharpness, POV and compositions are the best. Pictured fly is amazing in all respects too as well as photographer who has produced this masterpiece. My congratulations and Bravo.

Hi Anna,
A very good photo with excellent detail.
In New Zealand these are called Bristle Flies.
I posted a photo of one of ours a few months ago.
This one is cool.
Cheers & TFS

Gerçekten çok etkileyici bir makro bu. Sineğin detayları ve özellikle gövde üzerindeki tüyleri çok müthiş görünüyor. Yeşil zemin üzerinde gölgesiyle birlikte enfes bir kompozisyon oluşturmuş. Tebrikler.

Hi Anna

You have done very well indeed, its a fine shot of this unusual fly. I do agree that until you start taking macro shots like this you just don't appreciate the delicate beauty of all creatures great and small.
I like teh composition and of course teh sharpness; the shaddow is an interesting addition to the shot.

Chris

Hello Anna

excellent pose, POV and a like the shape of the shaddow
Have a good night

Hello Anna,

Fine details have been captured in this amazing insect!
Excellent macro work with pin sharp details, and I notice the fine texture in the leaf he is sitting on...
The composition is balanced with nice use of the shadow!

Hello Anna,
I'm really glad you too enjoy the micro world of flies! It is so fascinating and I've often thought it a great shame that not more is shown about the micro world of insects on TV where instead endless films about the great beasts, lions, etc. are shown.
This is a superb capture of this 'bristle butt' showing fantastic details and colours in good light. I like the shadow too and your fine composition.

This fly is very impressive with all these prickels on its back. We have a species very similar which is called in German Igelfliege (hedgehog-fly too). A very sharp and well composed shot. Very impressive to see its shadow, makes the picture special.
Thanks also for the note and WS-picture

Dear Anna!

Many thanks for your recent visit in my gallery. As you can see, I'm not often present on TN, too. The evenings are so long and fine now that I'm less sitting in front of my computer...

You present us a fabulous picture. It is of a rare quality, and I'm impressed what you can do with your Cybershot. The sharpness and especially the clarity just are superb and reveal so fine details. The lightplay, particularly the shadow created by the insect and reflected by the leaf is magnificent. It is as we would have two insects in the picture. Moreover, it seems that they look at me... the composition creates this effect. One can feel that this is not just a lucky shot, but the result of a photographer's eye and work...

Congratulations, many thanks and kind regards

Markus

Really like this long shadow cast Anna, interesting light.
Great detail and comp too..The common name sure fits nicely as well :)

There should be no doubt as to why you decided to call this a porcupine fly, what a strange looking little critter!!
The detail is amazing and the colors are just gorgeous. Love the lighting in it's wings, as well as the excellent DOF you managed to capture. The workshop photo is of equal quality!!!
Super job!!!!
