Biology

Castes

(Ito 1997) - Ergatoid queens of L. myops are exceptionally large in body size (head width 1.18 mm) relative to workers (head width 0.75 mm); other Oriental species show similar head widths between castes. L. myops queens have 32-34 ovarioles per ovary while workers have 3 ovarioles per ovary. In contrast, other species have same ovariole numbers between castes.
