Insect baits

I realize that there are doctors among the forum members, but I answer this way - I was waiting for them (morfid).    

Now in the middle zone, most of the insects are already in a state of diapause or close to it, so there is no special point in catching baits anymore. Look forward to next season.

Yes, yes, yes
please tell me what you can still bait goldsmiths with

I did not catch them, but I saw a few goldsmiths fly to the crushed bananas

So big? I thought it was a small thing. Could you describe those goldsmiths in more detail?

What you can use for bait:
rhino beetle
swallowtail
polyxena
and barbel oak
The latter is not on any bait does not go      

.. A rhinoceros beetle can be lured to a cow's gamno that is so immature-compost is called, they live there ... swallowtail and polyxene can be lured to liquid gamno...

On this occasion, a couple of years ago, a good movie was on TV. There, a Canadian entomologist in South America caught morfid. Bananas, watermelons, Coca-Cola, sour wine, human urine (sorry) and a day or two in the heat. I tried this recipe myself personally.

By the way, the following bait idea came up:
The basic idea is based on the same traps for barbels-a jar, a bottle, but better some kind of bucket or something else larger with a retainer attached to a long rope with a sinker at the other end. We choose a crown or crowns higher, a protruding branch and throw a rope with a sinker. the rope clings and we pull the bucket with bait over it, so the trap is in the crown of the tree without much effort. we tie the rope anywhere, preferably to the same tree.
Maybe this will allow you to collect interesting insects that do not like to fly low and descend?

This is interesting!!! Please tell us more details, especially about the proportions: in what ratio to combine everything.

About manure and other fecal excreta: dung lamellae, staphylinids, water lovers come + some dead eaters
Who asked about goldfish: mowing, window traps, visual inspection of freshly cut trees. As for turpentine, it is possible, but coniferous species are more likely to use it. I haven't tried it myself, but I'm going to.

I usually use 5-liter baklashki from beer or min. water

 
And let's talk about ethyl alcohol: is it worth noticing it as a retainer for traps, does it spoil the color of BEETLES

Ethyl alcohol makes insects tough and difficult to fix.

In my opinion, the most terrible thing in this sense is FORMALIN!!! To somehow save yourself from this scourge, I suggest adding ethyl acetate in soaking, this is certainly not a panacea, but still...
What about glycerin??? What are his sv-va, how many traps can withstand?

P. S. May the moderator forgive me - I know that I am moving away from the topic of discussion. You can highlight the new topic "Fixers for traps"

Ethyl alcohol makes insects tough and difficult to fix.

I often met goldsmiths and barbels in the sawmills. And I came up with the idea to take the essential oil of some coniferous tree, dilute it with a solvent (so that it is not much consumed) and add it to traps or near them. In theory, mustaches and zlatki should arrive. Can someone thread already tried this?
