Which pest is described as slender brown-reddish, with cream-colored larvae and is found in dried fruits or cereals?

In stored-product pests, matching both adult appearance and larval form to the typical food we find in storage helps identify the species. The description—slender brown-reddish beetle with cream-colored, legless larvae found in dried fruits or cereals—fits the saw-toothed grain beetle best. The adult is a small, flattened brownish-red beetle with distinctive saw-like notches along the sides of the prothorax, and the larvae are pale cream-colored feeders that attack cereals, dried fruits, nuts, and similar stored foods. This combination of traits and the typical food substrate is a classic sign of this species. Other pests don’t fit as cleanly. For example, Indian Meal Moth larvae are caterpillars that feed in webbed masses and are accompanied by a moth adult, which looks very different. Granary weevils have a long snout and their larvae usually develop inside whole grain kernels rather than freely in dried fruit or cereal products. Cockroaches have different body forms and life stages and aren’t described by a cream-colored larva associated with stored dried foods.
