Caught the eye of an interesting type of traps used in the Arctic desert, under extreme fishing conditions.

And how do they work?

This trap seems to combine several principles.
First, the greenhouse principle. Heated air, as far as possible, of course,

does not "blow away", as well as imagos coming out of the soil. By the way, temperatures on this island (see the article in the footnote) have a very small spread - less than, for example, in Moscow: (extreme) from -15 to +5.
Secondly, the principle of the window trap ("invisible" barrier).
Third , the principle of the Malez trap, when flying insects that have fallen under the dome for various reasons, due to positive phototaxis, accumulate in the upper part of the trap dome.

anyone read the works - what was caught?

This is more of an informational message. Direct translation: ticks 116 species, spiders-18, collembola-59, insects-231. Specifically, the text mentions only 1 type of collembola, 1 fly and 1 aphid.
