In both natural and captive environments, these arthropods occupy key trophic positions that regulate ecosystem dynamics and contribute to the stability of arthropod communities. However, in captivity, whether in laboratory research, zoological institutions, or the collections of private arachnid enthusiasts, the feeding regimens employed are often generalized and fail to consider the biochemical specificity and metabolic demands inherent to spider physiology (Toft, 2013). Surveys of spider keepers and field studies confirm that prey selection is frequently based on convenience rather than nutritional congruence (Survey Output, n.d.
