Post Unidentified 'Bronze' Soldier Fly
The mention of of Detritivores reminds me of a fly that definitely falls into that category, but one which I have been unable to identify. Looking through Google Images, I cannot find anything which has the distinctive blue 'saddlebags' under the wings. They must be a close relative of Hermetia illucens, because they have the same habits. The grubs also live quite happily together with BSFL. I was wondering if anybody had an idea?

This fly is slightly smaller than BSF, and note the distinctive blue 'saddlebags'.

The eggs appear to be identical to BSF.

The small dark ones are the 'bronze' grubs.________________________Note the pretty zig-zag stripes. You see the big BSF pupae on the left.

I sent a message to Dr. Norm Woodley. Let´s see if he can help us.

Mr Norm Woodley replied me:

The "bronze" soldier fly in the photos that you sent a link to is Cephalochrysa rufibasis (Walker), and occurs in South Africa. It seems to be fairly common because I've seen it in several collections.


In the name of our forum I´d like to thank you for your attention!

I wonder if these are halteres (link)?

Halteres (pron.: /hælˈtɪəriːz/; singular halter or haltere) are small knobbed structures modified from the hind wings (or front wings in the case of Strepsiptera) in some two-winged insects. They are flapped rapidly and function as gyroscopes, informing the insect about rotation of the body during flight.

Two more shots of C rufibasis. They are rare visitors these days, the BSF must have pushed them out. :(
