At the start of hot weather flying ants love the shiny top of the toroid (well what do you expect of Queens?).

Most probably died acting as breakout points when they touched on my toroid.

7 of the confirmed kills landed on my plastic box sitting on the primary.

Even the big ants fly here. These are normally fast aggressive and vigilant ants that will turn towards you with a threatning pose. Nasty sting too.
This one was more quiet and I took about 30 pics of this flying bullant with my free hand while it crawled around on my other hand It mostly wanted to go up so I kept changing the tilt on my hand. The posturing would have been worth a YouTube video in its own right.

Peter-

Very nice macro shot of the big ant; I assume that both that both the camera and the finger with the ant were unsupported during the shot?

May I ask what make & model camera was used?

(I'm shopping for a new digicam for use at work, and excellent macro performance is probably the single most important feature.)

Regards,
Scott Hanson

The world's most elaborate bug zapper...

TDU, when they got hit was there anything to indicate they got hit? I imagine with enough power, they'd do a nice job of creating a little cloud flaming debris that could give the impression of 'ball lightning'.

(Note: Any discussion in this thread about ball lightning being caused by bugs will be laughed at, and then deleted)

Shan, we've got a great many talented photographers on the board. A thread asking just such a question would probably give you the best participation.

I don't really think they got "hit" and it is unlikely for there to be sufficient resistance /power to burn a flying ant. No balls of fire. Most likely scenario is they are flying above the TC, the e-fields give neural disruption and they fall onto the toroid then act as a breakout point and die.

Much twisting and turning from both hands. In many shots the antennae were too blurred as they flick around a lot.

Think carefully before you buy a camera. A good proportion of my website success has been able to take long exposure, low light photos with a digital SLR. I could not have done many of my shots with my other point and shoot cameras. It's not just the pixels, in fact 90% of the time people only see less than a 1MP photo (camera is 6MP).
Without the manual exposure option I would not have been able to take 3 of my top 4 photos and this more than anything sets my site apart from others. I was fortunate enough to win it because things were changed thereafter and I would not have had the opportunities that I have had.
I would buy a DSLR second hand rather than a new point and shoot if the money was the same.
It's a Nikon D70s, but that's not important as it's the manual/long exposure option and better low light capability that matters to me. Tripod is essential and remote triggering is important.

The Bullant (Myrmecia gratiosa) was identified by an entomologist. South-western WA.

I think that making a breakout point from a bug would turn it into ash! (even metal is beeing melted!). I think the important killing factors could be also the ozone, high temperature and maybe the UV light...

Despite it is probably the most unefficient insect killer I've seen I like it a lot smile

There was no visible corona from the toroid as I had a 2 foot rod that was making sparks. Also only very short runs.
I forgot to connect my earth initially and the coil was functioning outwardly normally. I noted the primary to sec arcing and connected the earth but the coil remained "wrong" and was triggering my safety gaps which have never fired before. I took a few flying ant photos during this.
I tried a shorter lead to the earth, 2 earths, counterpoise plus earth before I realised that a sparks had occurred across my rotary gap and had carbon tracked deep into the phenolic disk.
The pic shows the damage.
I have now used an angle grinder to gouge out the carbonised area and a similar sized one on the other side for balance.
Fingers crossed.
I would have killed the lot if I left it running for any length of time.

>.< carbon tracking on your sparkgap? that stinks. Hope you can get it up an running again.
