Meccus dimidiatus uses its toxin primarily as a means to subdue its prey. The venom is delivered through its mouthparts, which are specialized for piercing. In its adult stage, meccus dimidiatus can cause mild discomfort to certain groups of animals, such as insects and arthropods, through a bite. These animals may experience varying reactions to the toxin, though the intensity is typically mild and not life-threatening. Smaller creatures are especially at risk of being affected by the venoms of meccus dimidiatus due to their size and physiological vulnerabilities.
