In the second part of the article 31 species of Lepidoptera known from the Rostov-on-Don area were observed. They are, from the following families: Noctuidae, Geometridae, Sphingidae, Lycaenidae, Pieridae, Cossidae, Zygaenidae, Lecithoceridae, Tineidae. They belong to 8 relic and pseudorelic groups: calcareophyllous and petrophyllous pseudo-relicts, halophyte deserts pseudorelicts, east-Asian steppe pseudo-relicts, xerothermic steppe pseudo-relicts of the early Holocene, xerothermic Mediterranean relicts of the early Holocene, conditionalrelicts, pseudo-relic complex of stony steppe, Caucasus forest relict of the early Holocene. Disjunction of areas, rare occurrence and degradation of zonal populations by anthropogenous factors are characteristic for the pseudorelicts. In particular, rare steppe endemic species, for which natural habitats are being destroyed, become pseudorelicts
