Urgently!!!!! There's a guy making a movie here. A scene is being shot where butterflies arrive at the light. Please tell me which lamp is best to take, because there is no need to prick the bulb and in general it is desirable that there is normal light, but that more or less large butterflies are attached. Tell me how many watts, etc. He said he could get a 500W lamp, would it be better than a 250W one or not?? And it is also desirable to tell me in what area it is better to catch, maybe near the forest or in the field or somewhere else, I want the hawk moth to fly-it will look more spectacular and I will then collect something.. At what height is it best to hang and the air temperature should be what, at what time to turn on the lamp, what will be the main time of years and so on!?!? PLEASE TELL ME!!!! Your feedback is very important!

In general, thank you to all those who sympathize and participate!

Today, "putting on clean underwear and praying," I connected all the wires and made a test run of the lamp. It's on fire!

However, the TV and radio jamming only so (throttle works?).
Only with the breaking of the flask, I overdid it - I split both

How do you beat them so neatly? I, like, tried to hit the side of the lamp a little bit, tangentially, and wrapped the rags in several layers - it still didn't help. Only later, however, I thought that, probably, it was still possible to: a) wrap it with tape, and only then beat it with a hammer; b) make several incisions with a glass cutter and prick them; c) do not beat, but gently crush it in a vise (I like this method better, you can apply dosed effort); d) my wife advised me to dip it in boiling water, and then in cold water.
What do you think is preferable?
And also-in the inner flask, because mercury vapors glow? How big is the risk of over-inflating them if the inner flask is also broken?

Pancake.. Well, at least the flask wasn't smashed in the room? It's full of mercury, almost like a thermometer. It's very easy to hit - wrap it in a rag and hit it with a sharp something, a knife or something like it, you just need to calculate the blow. Well, how many of them I beat - I never broke it in the morning, there's also quartz glass, what did you beat it with?
Mercury poisoning from the flask immediately "in one day" is practically impossible, nothing terrible, it is dangerous with prolonged exposure. Therefore, it is better not to break these lamps at home.

What affects the TV is not so much from the throttle, but from the entire complex as a whole. A discharge lamp, RF oscillation induction, etc. There is a way to put a filter, but in principle it will go like this.

No, not in the room, on the landing... However, I wrapped it in several layers of rags and in a plastic bag. I don't think I noticed any metallic mercury there, is it in the form of some kind of compound?

I hit him with a hammer, as they wrote somewhere...
Today I will buy a few more lamps, I will try to break them carefully, for example with a chisel.

Another method of collecting moths.
I'm not the only one who uses it, and I didn't discover it, but I need to remind you.
If somewhere in the country, in some gardening association is full of lanterns with DRL and DRV lamps, then early in the morning, literally at dusk before dawn (to catch up to insectivorous birds), you can walk around and see what has flown to them. You need to inspect not only the pillars, but also everything within a radius of 5-10 m. In order to get a high-sitting butterfly, I use a kind of small shallow net attached at an angle to a long telescopic rod. The sitting butterfly is removed from below, falls into the "net". Rarely, very rarely does it fly away. It is convenient for collecting tufts, which often sit high, right under the lamp.
Such, here, a little duremarsky method.

Last night I tried out the lamp on the glass-enclosed balcony. Since only 1 sash opens, the lamp had to be hung just in this open sash, almost on the street, and the screen was very much behind (see 70 exactly before the lamp was) - many insects landed on the glass of the non-opening sashes. It didn't fly very much, mostly dipterous mosquitoes (chironomids, some Gallica, even the fly Sarcophaga sp.

). From the butterflies-3 different scoops (one, I think, Cuculia sp.). There were a lot of caddis flies (1 species; the proximity of the river affects). Oki is about a kilometer away). What I did not expect at all - a reticulate wing from the family flew in. Hemerobiidae - Drepanopteryx phalaenoides. Caught somewhere before half-past midnight.
I protected my eyes and face as best I could

In the morning with my eyes all right, I looked in the mirror - "and the muzzle is red"

Yesterday I also caught the light. A lot of things arrived, although I expected more. A silver crested bird flew in, several species of moth - about 5 species of gray, 1 red, and various other small species, I didn't even count how many.. there are many types of scoops, 2 of them are cool - 1 large gray, the other gray with a green shiny pattern. 1 kind of silkworm, like from the unpaired ones, such a white one, with a beryuz shade. 1 type of cocoonworm, like oak, 3 pieces, but all pokotsannye. 2 riders of the same species, a lot of bees (I caught on pasik), about 4 of the most common (white) types of bears, and other small things that I didn't pay much attention to. The lamp is not yet split, caught on the whole. If there were better conditions for installing the lamp, then perhaps the catch would be better.. But there were no purebreads at all, and it was a pity

The report is passed, I have scored new types and am generally happy, I hope there will be more next time.

Well, I also caught something at the dacha.
Just like last time, he turned on the lamp in the attic room, and he "waved a net" under the windows.
On the night of the 11th, it was overcast and quiet. Caught up to 2 nights. We flew well. Different crested birds arrived after an hour, as they should. The ocular hawk moth arrived at dusk, around 23:40, and a couple of medium-sized wine-after one o'clock in the morning. Scoops of all sorts, a lot of moth, spread out, now I will understand-there are interesting specimens. It is full of bears (however, as usual) Spilosoma lutea and Spilosoma lubricipeda.
The next night it got a little colder, with a huge full moon and a chilly breeze. It must have been a lousy year.
