Found this small dead scorpion in my electrical stuff.
This is a pic taken under UV of peak wavelength 253.7nm. The unit is a Model 753UVA from Sirchie Fingerprint Laboratories inc.

Nice fluorescence.

Lots of insects, scorpions, etc. have flourescent skin that reflects UV in such way.

Once I found a roasted lizard inside emrgency lamp, got inside HV inverter and blew together with it.
Pity i didnt take picture of it...

When I first got my FBT driver working, a ladybug (we have thousands of them at certain times of the year, you can't hardly stand to go outside on some days) landed in front of me. So, "somehow" he "accidently" got between the HV probes. I thought he was dead, and he was smoking for quite a while longer, then 5 min later, I came back and he's crawling around!!! Resilient little devils, no wonder there's so many of them. They smell terrible, and I'm talking about before you burn them! They gather by the hundreds in the corners of our ceilings, and we have to vacuum them out. It's disgusting, we finally figured out where they were coming in, and put a stop to it though.

Yeah, we get the same thing. They're not the normal ladybugs we used to get, we don't see those anymore. At least they are only passive pests.

Cool picture, TDU.

If by "normal ladybugs" you mean the spot count.

The farmers buy the ladybug cards to control the aphids in their gardens /green house.

I have seen service panels with dead moths, cockroaches, rats, mice, beetles, and or snakes. Cockroaches and mice I would say were the most common.

Scorpions shed and usually eat their own skin.
Mmmmm, yummy... lol =]

These little scorpions come in under our front door and then seem to end up in the corridor under the light at night along with assorted earwigs and spiders.

I have never had one around at the same time as I had a UV light available.

Ants are the big problem. Termites are riife and will track long distances in their tunnels across my shed floor to get at a tasty bit of timber. Other ant types seem to enjoy getting into the meter box and recently an electrican tracked down a fault to ants in an apparently sealed 240V relay. He says they love the contacts for some reason.

Pic below is of a flying bullant that I found in our drive. Normally very aggressive vigilant ants with a nasty sting.

Sweet. Glad we don't have things like that here in the Eastern US.

This is another UV shot of the same scorpion but in near UV with black light fluoro tube.

A croatian monster.
Soldiers grow really big, over centimeter long.

Vary agressive, they make interesting ''roads'' while moving, and bit everything in way (there is no grass on ''roads'' , they cut it off)
I dont know how to translate their name, maybe wheatcutters?

Only one specie is larger but that are friendly black ants that live usually on islands and coastline, in small colonies.

Wood ants (black with red heads) usually put you to ignore list until you disturb their colony (piece of wood their queen lives in) good idea is to run away guickly (bites + miniature poisonous sting)

So much for bugs, yep good pictures TDU

One thing to note, do not expose a live scorpion to UV. I've heard it over and over, but apparently it is quite deadly for them to be exposed to UV. Scientists use the UV to find them in the desert, but porolonged exposure (think minutes) can and will cause them to die.
