What contrasting feature is present on the larva of *Endrosis sarcitrella*?

A brownish or darker head capsule

Although the adult moth is the stage most often observed flying, the larval stage possesses its own distinct morphological features. The body of the larva is typically described as being creamy-white or pale overall. However, this pale coloration is contrasted by a specific feature: the head capsule, which is noticeably brownish or darker in shade compared to the rest of its body. This contrast between the pale body and the darker head is an important physical trait to look for when identifying the destructive larval form feeding within stored products or textiles, especially since the larvae also exhibit behavior like spinning silken threads as they move.
