Lamiacean flowers have specific floral features adapted to particular pollinators. The lower lip act as a flag to attract, and also as a landing place, while the upper lip shelters the essential organs, which are usually placed so as to touch the insect’s back in order to result in nototriby. This paper indented to bring out the correlation between Hymenopterans and Leucas sp.The lower lip of corolla length compare with insect body length and corolla tube length correlated with insect proboscis length. The measurements show that positive correlation between Leucas and Hymenopterans. Lower lip of corolla of Leucas members specifically modified for Hymenopterans and proboscis length also shows direct correlation. This result indicated that Hymenopterans were well modified for bilabiate Leucas members.
