Features of light catching

Yes, the sky was clear, but without a moon, starry. So, it's better that there are clouds.

Yes. When cloudy is the best year.

Djon'a on Khortytsia, as I understand it, has oaks, and the oak is the most eaten by butterfly plants (it has the most species). But there are also quite a few species on poplars and willows (in second and third places after oak).

I catch nocturnal fish in the spring and it is better to do it in the woods. Forest species begin to fly in February, and steppe species are already in May.

But not all March species have caterpillars that feed on trees, and there are some that live on shrubs as well. Ocnogyna parasita, for example, generally eats nettles and plantain. And the canister with the vaccine, ugh, Conistra vaccinii, in addition to trees, also feeds on blackberries, which are in the swamps; Conistra rubiginea - on rose hips (also there); Xylena exsoleta-on clover, milkweed, bedstraw. It turns out that the availability of forage plants is not as important as the biotope?

As for light sources, I am personally attracted to LEDs because they are safe for the environment, if they break suddenly or if they are thrown in the trash. In our region, I found on the Internet only one point of reception of light bulbs-housekeepers, and it is located in the regional center, and it is still necessary to find it.

About UV housekeepers: do I understand correctly that visible light in this case is not needed to attract butterflies, i.e. you can turn on one UV housekeeper and, if necessary, highlight the screen with a flashlight? Is the UV radiation of housekeepers harmful to humans and the environment?

Any light pollution is harmful to the environment. Catching insects is also not useful in most cases. So this case is generally contraindicated for a true Greenpeace person.

Yes. Forage plants are a mandatory condition, but not sufficient for the species ' habitat. A simple example is that nettle is widespread in the Crimea, and hives live only in the mountains, from about 1000 m and above.

"Different butterflies are attracted to a different spectrum, as I understand it. For example, I found Xylena exsoleta near a low-power incandescent lamp. As for the UV housekeeper, I've never had anything special flown to her. Except for a few micro types.
- I think this question is better to ask the doctors.

 

Is the UV radiation of housekeepers harmful to humans and the environment?

Try not to look at the lamp that is turned on,as corneal burns may occur . There may also be actinic cheilitis ( dryness, fluidity of the lips due to increased sensitivity to UV radiation). It is more dangerous, of course, to damage the eyes.
And it is better not to look at other types of lamps ( DRL,DRV).

In principle, I knew this, we discussed it already, but I thought that this applies to places that are completely different from each other, for example, the Southern Coast of the Crimea and the Crimean Mountains from 1000 m, or the Crimea and the Moscow region. And it turns out that in one Kherson region on the same plants butterflies can not be just because these plants do not grow in the forest, and in the steppe.

Some strange conclusions and not correct.
The biotope itself is a consequence of climatic and other factors. conditions.
High in the mountains of the Crimea, there is a permanent snow cover, as in the Moscow region, but in the South Caucasus and the Kherson region there is no, whether it is a forest or a steppe

Yes, and more than that-the steppe of the steppe is a discord.
Different species have different requirements for biotopes. One species has a wide ability to adapt and occurs widely, another does not occur too widely, and the third is suitable only for a few places with a specific set of conditions. It happens that a butterfly lives here, and then it seems to be the same biotope, but something doesn't suit it anymore.

As for the UV housekeeper, I've never had anything special flown to her. Except for a few micro types.

Here is an example of flying to the left of the housekeeper, on the right is an ordinary housekeeper, which in itself did not give a result.

It seems to me that not an unimportant issue, this is the protection of light bulbs from rain. And in an open area, this can be very, very difficult to do. Who uses what devices?

Any light pollution is harmful to the environment. Catching insects is also not useful in most cases. So this case is generally contraindicated for a true Greenpeace person.

Well, a "true Greenpeace person" is generally an "abnormal outlier" that has nothing to do with reason. This is even worse than "blue"... much Worse!!! We found someone to look up to!

Well, I do not look up to them, and I am a poet and ironic about Wave Storm, who is worried about the scanty amount of mercury in light bulbs, which, I hope, is still not going to break with grief from the next non-arrival. By the way, yes, this is just the perfect night for fishing: the moon is right, and the phenological summer has started abruptly, it should be "zhor" .

Colleagues, please help me figure this out:

I purchased the above-described lamp for two 8-watt tubes with a built-in rechargeable battery:


I left one ordinary tube, removed the ceiling lamp, and inserted it into the second socket.:


So far - only disappointments(((

1) On the first days of May, I shone a light in the forest on the bank of the dam (Mos. region Solnechnogorsky district), the only relatively warm night was. On the steep slope of the old dam, I put a sheet, and on top of this miracle lamp. The darkness is absolute. As a result, it is perfectly visible from all banks for 300 meters. But, the "screen" itself is not lit, because the lamp shines "from it". And I walk around in circles with a powerful headpiece. In the lake - you can see frolicking acilius. Granulatus, nemoralis, dead beetles and leaf beetles run around on the ground. Small scales occasionally curl around the forehead. And on the miracle lamp - a couple of some midges and all. Out of season, I thought, and left.

2) On the second day of May, I flew to the Belgorod region. The weather forecast was good, I thought that I would be flooded with beetles there. The first troubles were waiting for me at the airport: with this lamp, you can't just pass through the frame. Both in Sheremetyevo and Belgorod, on the way back, I was forced to get this crap, explain something, call somewhere, I swore that it was in my luggage, and in the end they let me through. The second trouble is that it got very cold and rainy. As a result, manual fees are beggarly. Well, okay, I think now a miracle lamp will save me. I hung a sheet on the fence, facing the fishing line in 100-150 m, and on top - the device (also facing, sopsno, "prey", and back to the screen). Well, let, I think, at least melolontha melolontha will fly (and they are near the lanterns-met). Two hours of glow and a couple of midges. Out of season again((

3) Yesterday I again went to shine a light in my forest near the same dam and by the same method. Everything is covered in dew, there is almost nothing on the ground, rare moths flicker around the head lamp, once melolontha hippocastani flew not far from the lamp, but was not interested. And on the miracle lamp-again a couple of midges (probably the same). I return home, where I knowingly hung such a 25-watt lamp on the balcony (a good lamp, I often take it with me if I have somewhere to stick it - a lot of beetles fly, and it shines all around-both on and off the screen):


And there, on the balcony, damn - a real hive of May beetles is spinning, despite the good street lighting around.

Now the questions are:
1) Out of season?
2) Lamp-shit?
3) Maybe I'm doing it wrong and I need to shine a lamp into the screen, and not from it (it seems to be mentioned a little higher)? Although I don't really understand how this can work...

In a month I'm flying over the hill, I want to shine this crap there in the mountains, but now I think - does it make sense to carry it, a two-kilogram one?..

1) Now, in the Moscow region itself, except for May beetles and overwintered scales, nothing flies to more serious sources: out of season (cold).
2) It is advisable to put lamps not black, but like this: http://shop220.ru/product37479.htm
3) Put the candle in the direction of the vertical screen and flies well with the right external factors: (suitable weather, time, no extraneous illumination).
The main drawback:
Extremely unreliable acid, Chinese battery, which I covered with a copper basin very quickly. I threw out this ACC and instead of it I made a homemade block of six suitable lithium-ion 18650 batteries
, it's definitely not worth taking on a long journey.
Too unreliable due to the standard battery and the relative "flimsiness" of the design.
It is only applicable for driving not far from home and shining the light for 3 hours (the standard battery is not enough for more).

Thank you so much for the information!

And how is the proposed lamp better than a black one, in a nutshell? (I don't really understand it)

And how to shine "into the screen" - after all, then the actual direct light of the lamp around will not be visible?

1) The fact that it is designed specifically for light traps for insects. And the ultraviolet light in it is not extinguished to a safe level for the eye with a blue filter. Accordingly, it flies better on it. In short, you need to read the purpose of both lamps and draw conclusions
2) Why direct light? Ultraviolet light is perfectly reflected by the screen and a larger spot is obtained than the lamp itself. In addition, the screen itself remains visible to the eye when you look at what is sitting on it.

Vasily, please don't mislead people. First, in Blacklight 365nm fluorescent lamps (also known as BL 365), UV is not "extinguished" by a special glass lamp (Wood glass), it only cuts off visible light with a length of more than 400nm. Rather, short-wave UV below 310nm is cut off to a large extent, but at least to the same extent it is cut off in" special " BL368 lamps. Just BL368 is "crushed" by the density of UV radiation (measured in W/sq. m at a distance of 1m) to 0.25 milliVt/sq. m.m in accordance with the standards adopted in a number of countries (English EN60335-2-59: 1997 requires no more than 1 milliVt / sq. m at a distance of 1m, similar requirements exist in other similar standards). This made it possible to certify and apply them in passive light-electric traps of a short-range domestic type, i.e. for killing mainly diptera in restaurants and other public places. This provides a market that justifies their production, but this market has rather strict safety standards, which is also associated with the production of such lamps in the Toughcoat version (in an indestructible protective film). Naturally, BL368S are being promoted in all sectors of the market (they are also safe even for newborns) and are also offered for screen fishing, and a number of institutions, for example, in the United States, simply do not have the right to officially purchase and use "unsafe" alternative lamps and independently assemble lamps, but professionals for whom this is necessary it is important that these requirements are violated whenever possible in favor of BL365 lamps and their even more powerful gas-discharge analogues, since BL365, previously invented for other applications and less stringent standards, give ten times higher UV radiation density even at equal power, and since they are offered for sale and are mainly used more powerful compacts (26-40W vs. 8-13W), then the gain increases, including in terms of" range", which is very important. At the same time, they are much cheaper and more affordable to purchase. I must say that BL365 lamps are also relatively safe (they are allowed for use in discos, etc.), while observing minimal protective measures; in any case, they cannot be compared with "beaters".
Also, these two types of lamps differ somewhat in their spectrum: the BL368 has a narrower one, and the RELATIVE peak (in % of light output, including the visible part!) in the region of 368nm, it is more pronounced, but taking into account the significantly lower total radiation density, and in this region they give less than comparable BL365, and the difference in the peak of 3nm is relevant, it seems, only for marketing. In general, in my opinion, the idea that the closer the radiation peak is to 368nm, the better it is to attract insects (except for blood-sucking diptera), to put it mildly, is not sufficiently confirmed, the experience of using different gas-discharge lamps says just about something else.
I have already written about this in more detail and with supporting materials from lamp manufacturers when discussing "stand-alone" lamps from a well-known store, but I can't find a post, this is some kind of disaster on this Forum
2) The reflection of the UV screen depends on the type of fabric, if you catch it with indirect light, a special fabric is desirable, and the radius of attraction drops catastrophically. This is only justified for very weak battery-powered sources (for example, a 365nm 3W flashlight on a 18650 battery can shine on a small screen, and the attraction will be better than if you shine it from the screen).

Regarding the fact that I generally agree with everything, I will focus on two points:
1) I experimented with both types of lamps and I will say that in fact, in my practice, the BL368 flies in the same conditions much more productively than the BL365. Here I categorically refuse not to believe my own eyes and confirm
2) By the screen I meant an ordinary, white cotton cloth (a sheet, in short). This is where the whole thing was tested

You minimize your self-inflicted damage as much as possible by not shining at all. For you, catching butterflies is a hobby, not a science, if I understand correctly. But this is a slippery slope, along which you can get to the point of sticking a paper strip over your mouth to avoid accidentally killing insects that have flown into your mouth, as followers of a religion called Jainism do.

Well, first of all, it is 20W, not 250W. A comparison with a conventional 20W compact would be adequate. Secondly, you should not take completely unknown Chinese "brands", this lamp is unknown what shines. According to the description, the luminous flux there is "10-100", whatever that means, and the normal Camelion LH26-FS (3U) E27 BL 365 26W price in the same 500-600r gives about 560lm. For comparison, DRV 250 give 4500-5800lm. Third, if you are still using a high-power lamp, use low-power UV lamps with it, not instead. And the improvement will be noticeable, especially for twilight species.

Hi everyone, I can guess that this issue has already been discussed on the previous seventy pages, but I'm sorry.

What power generator is needed to start a 250W DRL?
And maybe you can name the proven brands.
Thank you.

I do not know such a generator that can not start the DRL 250 W
Honda EU10IT1, the most reliable and economical, but also the most expensive!
Kipor IG770 and IG1000 are three times cheaper, but there is a lotorea, it can work for a decade, and maybe the warranty period, then problems with repairs, all other inverter generators are even worse.
Two-stroke cars for one or two seasons maximum.

Question, to the point!
For example, I have an inverter Fubag TI 700 can not start the DRL 250, it stalls, but it easily starts two DRV 250s in turn with warming up.

Question, to the point!

Most likely, this problem is due to the throttle. If you have an old Soviet "box", then it can give a noticeable overload when starting the lamp, up to a launch failure. Try new chokes, easily found in electrical stores.

Osram has proven itself very well,from personal experience I will say that I am very satisfied with this lamp

Triple!
