Dry weight increase of queens and males of the ant Lasius niger after eclosion from pupa was estimated from sequential field samples of eight colonies. Queens increased from ca. 4 mg at eclosion to 15.5 mg at the time of nuptial flight, whereas males remained approximately constant at 0.9 mg (Fig. 1). Queen mesosoma and gaster increased in weight simultaneously up to a total of 13 mg. In queens in nuptial flight condition (≥13 mg) the weights of mesosoma+head and gaster were negatively… CONTINUE READING
