Znanstveni glasnik, 2002
Morfometrijske odlike praćene su na 79 uzoraka sive pčele sa slijevnih područja rijeke Bosne i rijeke Netretve. Na prednjem desnom krilu uzorkovanih pčela mjeren je kubitalni indeks, hantel indeks i diskiodalni pomak. Utvrđena je velika varijabilnost kubitalnog indeksa, kako unutar, tako i između uzoraka.
