Trophic interactions, the fundamental links in food webs, are an important modulator of biodiversity structuring and ecosystem functioning. However, interactions between scorpions and insects remain poorly understood despite their high biomass and diversity in natural ecosystems and more than 410 million years of evolutionary history. Here we summarize three trophic interaction types from 95 scorpion-insect species pairs in which both scorpions and insects were identified at least to the genus level. Predator-prey relationships were the most documented trophic interactions between scorpions and insects, involving 45 scorpion species from 9 families and 79 insect species from 11 orders. Prey-predator interactions were recorded between 11 species pairs of insects from four orders and scorpions from five families. Parasitiodism was documented between four dipterans (3 families) and five scorpions (3 families). The mega-diversity of insects and the high biomass of scorpion species in natural ecosystems imply that their complex trophic interactions await to be characterized.
