Harvestmen as a model to explain the aggregations of Macrohaltica beetles (Coleoptera: Chrysomelidae)

Neotropical beetles of the genus Macrohaltica form aggregations exceeding 5000 individuals, but there are no studies testing the four hypotheses available to explain why. Based on the better studied Opiliones aggregations, I propose that Macrohaltica aggregations were selected for three of the reaso...
