Insect baits

what kind of bait / trap is needed to catch such a beetle?

In the manure.

another option is a dung trap

is there a cow or horse in the bag? and what size is the bag?(cm)

and if it doesn't exist

and what do you think, if a piece of meat(chicken) is put instead of mash, the effect will be?

You are an aspiring sadist! Why do you hate butterflies so much?

For dead eaters, in the Tver region I put containers with chicken meat, they were perfectly caught. The main thing is that crows do not steal, they do it very well. I also wanted to try, but my hands did not reach, to pierce the egg, and in the jar, this is for a cleaner removal of dead eaters.

  
for a long time I want to try (I came up with it myself, but I saw analogs on the web) a trap for caprophages: dig in a bucket, a large grid on top, so that copra or geotrup can get through, maybe even a reed type (so that they can dig hard), and a "flat cake"on top. maybe someone tried this?

do they go for the egg too?)
and if the chicken+egg

if you love them, then just smear the trees with braga and look at them all night. who needs to be caught, but why make a mess / mass grave

In vain pinned (Ruined!) Velleius dilatatus, you'd better let him go.

  
maybe if you add a brew, an egg, some meat to them, then someone has to get caught

Yes, there are half of the arriving beetles and so escaped. I disdain to take them with my hands, but I didn't take tweezers with me. They're smelly, and the red ticks are running over them, and they'll crawl over me again. He tossed them into the water, drowned them, then dragged them into a box with a stick and stabbed them with ammonia-laced insulin.

Velleius dilatatus is a very rare beetle and is not worth being pricked, the beetle is large and it can be glued to the die. But that's what I think, and your beetle is really good, catch more of them.

Information about the great rarity of Velleius dilatatus is somewhat exaggerated. Probably, the generally accepted opinion about the rarity is due to the secretive lifestyle of the beetle and the fact that it almost does not come across by chance. This is a trans-palearctic species, which is found in Central Russia everywhere (including in localities) where there are large Vespa species. Regularly arrives at the light. It is not uncommon in soil traps with vinegar-alcohol bait (in my collections from the Nizhny Novgorod region to the south of Primorye).

Is it now possible to catch gammarus, water donkeys, etc. (in Voronezh)
if so, please share the technology

  http://ukrainefiherman.at.ua/index/mormysh/0-44 in general, gammarus is now sold in fishing shops - as bait. water donkeys - in any place of the reservoir inhabited by them are very common (squatted down near the water - with a dozen in sight immediately turns out-take it and catch it just with your fingers), if there is an unfrozen reservoir nearby-I think it makes sense to look there.
