A search for the pine-tree lappet moth (Dendrolimus pini (Linnaeus, 1758)) and Siberian silk moth (D. sibiricus (Tschetverikov, 1908)) was carried out by using sticky traps baited with synthetic sex pheromone blends.

In total, 32 moth species were identified from sticky traps intended for search of D. sibiricus: however, not a single Siberian silk moth was found. D. pini composed the biggest part of moths caught by traps for D. sibiricus, the frequency of D. pini was the highest, and it could be ascertained as not accidental. Other trapped moth species were revealed to be non-target. Two new localities of the occurrence of a very rare for Lithuania moth species, Bryotropha senectella (Zeller, 1839),...
