Besides stored grains and wool fibers, what surprising component feeds *Endrosis sarcitrella* larvae?
Answer
Droppings left behind by other stored product pests
The larvae of the White-shouldered House Moth are characterized as general scavengers with a remarkably broad diet that extends beyond typical pantry items or textile fibers. A specific and key element of their sustenance includes the waste materials generated by other pest species residing in storage areas. This diet incorporates debris and fecal matter left by organisms such as clothes moth larvae or dermestid beetles. This ability allows the moth to successfully colonize areas previously infested by different pests, essentially utilizing the residual organic waste left behind, which makes remediation more complex as the food source is less obvious.
