Lelo, S.: Variation of saccus length in the population of Leptidea sinapis Linnaeus, 1758 (Lepidoptera, Pieridae, Dismorphiinae) from wide area of Sarajevo. Prilozi fauni Bosne i Hercegovine, 2: 1-7. On this paper are present data about range of vary of aedeagus with males of Leptidea sinapis (Linnaeus, 1758) from wide area of Sarajevo. Have noticed that this character in sample of 267 individuas vary in range till 1,37 mm to 1,80 mm these that noticed range of vary in observed population are some higher than in literature data.
Key words: Leptidea, sinapis, reali, aedeagus, variability, variation.

Tallness of aedeagus, beside others characters, is a standard metric character in investigations of butterflies. Analysis of literature data was shown that this character in numerous papers has used only for comparing among specific species and very often on very little number of individuas. Meanwhile, very interesting question is which range of vary have this character in specific population these which are belonging of eventualy different fenotipic variants, relatively which are frequency of individuas per different category. Such system of analysis shoud provide very precise notice of range of vary some, very important metrically characters, especially if thay represent basic systematical character, i.e. if we use it, or thay, in determination of specific taxon, what is exactly in this case among species L. sinapis Linnaesu and L. reali Reissinger.
Analysis of tallness of aedeagus of 267 males of Leptidea sinapis Linnaeus of population from wide area of Sarajevo has shown that this character have range of vary among 1,37 mm and 1,80 mm. Noticed range of vary is considerably higher in compare with available literature data. Comparison of population average values ( – 1,606) with averaga values of subpopulations ( A – 1,607; B – 1,606) have shown high accordance and what purpot on genetical stability of this character. Values of coefficient of variability are small and very similar among subpopulations (V% A – 4,91; V% B – 5,11), what purpot on genetical stability of this character, too. Comparison of values among spring and summer generations has clearly shown a trend of decreasing of this character through generations (subpopulation A: I – 1,655, II – 1,570; subpopulation B: I – 1,667, II – 1,580; total in population: I – 1,658, II – 1,573 i III – 1,543).
Based on all notice data have make three categories these thay are conditionally named like three different fenotips:
short aedeagus (1,373 mm – 1,516 mm),
midle aedeagus (1,517 mm – 1,659 mm),
long aedeagus (1,660mm – 1,802 mm).
Comparison of relativ participation of sporadic categories have shown that among subpopulations values and population values most frequency category is midle aedeagus (% A – 59,89; % B – 51,25; % total – 57,30). Meanwhile, comparison among generations has shown that in first generation is most frequency category of long aedeagus (% A – 47,50; % B – 57,69; % total – 50,00) and in second (and third) generations category of midle aedeagus (% A – 71,03; % B – 59,26; % total – 67,08) on proportional increasing of category of short aedeagus.
Comparison of notice differencies by t-test hasn`t shown any statistic significance among compare categories.
