			| Description: | 
			  | 
			This species is a highly granivor ant which collects all kinds of small seeds and chew them to so- called antbread. Most of their waterrequirements are covered through seeds and insects.  Honeywater is only accepted when there is a lack of moisture. Messor structor tends to drown in open water so it is necessary to cover waterplaces with little stones or cotton. |
