<div><p>Research of hamuli of <em>Apis</em> have done at altitude 0 to 1400 m, in West Sumatra from December 2009-July 2010. Bees have collected from fruits, coffee crop and side of forest which are distances about 200 metre for each altitude.

Subgenus<em>Megapis</em> consisted of one species that is <em>A. dorsata</em> Fabr. Number of hamuli of worker bee have been variated, depent on bee types and habitat. Number of hamuli of <em>A. cerana</em> between 13-22 (average 17.7), <em>A. dorsata</em> between 22-30 (average 26.53) and <em>A. andreniformis</em> between 8-12 (average 9.84).</p>Key words: <em>Apis</em>, hamuli of worker, altitude difference</div><div> </div>
