A. tumida eggs are pearly-white and
about 2/3 the size of a honey bee egg (Fig. 1) and can usually be found in
typical egg-clutches (Lundie 1940). Normally, eggs hatch in about three days,
occasionally in up to six days (Lundie, 1940). In low relative humidity, egg
hatching may be reduced (Somerville, 2003; Stedman, 2006).
