Correct.
It's spring and the bugs are out. Earlier in the day I took a pic of flying ants on a background of a bloodred sun from bush fires (but it didn't show the ants).
The small flying things are small flies, and the larger ones are moths, and flying beetles including water beetles.

Other pics show the details.


Last pic with the Green stuff is the next mystery object.

Correct.

I suppose being from Oz helps.

Just I snap I took of a Banksia while bushwalking about 50 m from our house .

Pic shows the original.

I'll have to get something harder - like only showing one pixel wink

A closeup shot of a sunflower that hasn't bloomed yet or some other flower.

Mystery 82

I think, it is a plastic foil (most likely PP transparency for printers) placed between two HV electrode (small Marx or stun gun)... In fact we could call it a Lichtenberg figure.
