RESULTS AND DISCUSSION
3. STRATEGIC REGIONAL REVISIONS
3.1. REVISED FAUNA OF THE NEPTICULIDAE OF LITHUANIA
Intensive field work in Lithuania from 1996 to 2003 confirmed the occurrence
of 73 Nepticulidae species; 12 of these species are new to the Lithuanian fauna:
Stigmella nivenburgensis, S. crataegella, S. ulmivora, S. benanderella, S. continuella, S.
poterii, S. ulmariae, S. hemargyrella, Bohemannia pulverosella, Ectoedemia turbidella,
E. klimeschi, E. subbimaculella (Table 1). A further species new to the Lithuanian
fauna – Tischeria dodonea – was among the Tischeriidae.
A few species, reported in the past by other authors, have been excluded by us
from the revised list of Lithuanian nepticulids. Two species (Stigmella mespilicola
and Ectoedemia spinosella) appear to have been recorded originally from incorrectly
identified mines. We have been unable to confirm the occurance of three species
(Stigmella sakhalinella, S. sanguisorbae and Ectoedemia angulifasciella) either by
field-work or from data on material in existing collections.
The author’s research has demonstrated 15 plant families and 32 plant genera
as host-plants for Nepticulidae in Lithuania. Most of the species in the Lithuanian
fauna are trophically associated with plants from Rosaceae, Salicaceae, Fagaceae
and Betulaceae; the first – Rosaceae – strongly predominates and is the hostplant
family for 24 nepticulid species (fig. 7).
Two seasonal peaks for nepticulid larval activity (mining) were recognized:
from mid-June to mid-July (when 36 nepticulid species may be found mining),
and from mid-September to mid-October (when larvae of 49 species may be
found) (fig. 8).
