Where does most digestion occur in predatory ground beetles, contrasting with the typical herbivorous beetle system?

Answer

In the crop

While digestion typically occurs in the anterior midgut for many beetles, predatory groups like the ground beetles show that most digestion happens in the crop, suggesting deep evolutionary roots for plant-feeding in the lineage.
