Silkworms

Red-footed Tortoise

Chelonoidis carbonarius

Red-footed Tortoise is an omnivore with up to ~10% animal protein permitted. Silkworms are not explicitly listed for this species in the source context, but their favorable Ca:P ratio and low fat content make them a reasonable occasional protein source within the permitted animal fraction. Confidence is reduced due to absence of direct source citation for this species.

Yellow-bellied Slider

Trachemys scripta scripta

Yellow-bellied Sliders share the same dietary pattern as Red-eared Sliders per Merck Vet Manual guidelines for freshwater omnivorous turtles. Silkworms are explicitly listed as safe for Red-eared Sliders by ReptiFiles and are appropriate by dietary analogy for this closely related species.

Painted Turtle

Chrysemys picta

Painted Turtles are carnivorous as juveniles and omnivorous as adults, consistent with Merck Vet Manual freshwater turtle guidelines. Tortoise Trust confirms crickets and similar insects are appropriate occasionally for aquatic turtles; silkworms' favorable Ca:P and low fat profile support their use as a quality occasional protein source.

Eastern Box Turtle

Terrapene carolina

ReptiFiles explicitly lists silkworms as a safe protein source for Eastern Box Turtles. Their favorable Ca:P ratio and lower fat content compared to mealworms make them a preferable feeder insect option within the substantial animal protein component of this omnivore's diet.

Red-eared Slider

Trachemys scripta elegans

ReptiFiles explicitly lists silkworms as a safe protein source for Red-eared Sliders. Their better Ca:P ratio compared to most feeder insects and lower fat content make them a quality component of the protein fraction for both juveniles and adults.

Leopard Tortoise

Stigmochelys pardalis

Leopard Tortoise is a strict herbivore requiring grass-heavy, high-fiber diet. Tortoise Trust notes Leopard Tortoises are particularly vulnerable to dietary imbalances; animal protein including insects is contra-indicated for all herbivore tortoise species.

Greek Tortoise

Testudo graeca

Greek (Spur-thighed) Tortoise is a strict herbivore; Tortoise Trust explicitly categorizes animal protein including insects as high-risk and inappropriate for terrestrial herbivorous chelonians. Renal and hepatic damage risk is well-documented.

Russian Tortoise

Agrionemys horsfieldii

Russian Tortoise is a strict herbivore requiring high-fiber, low-protein plant-based diet. Tortoise Trust explicitly advises against animal protein for herbivore tortoises; excess dietary protein causes renal damage and gout in terrestrial chelonians.

Sulcata Tortoise

Centrochelys sulcata

Sulcata is a strict herbivore with a grass-dominated diet; animal protein is categorically inappropriate. Tortoise Trust and ReptiFiles both confirm no animal-derived foods for Sulcata, with high-fiber plant matter being the only appropriate dietary base.

Hermann's Tortoise

Testudo hermanni

Hermann's Tortoise is a strict Mediterranean herbivore. Tortoise Trust and Merck Vet Manual both confirm herbivore tortoises must not receive animal protein, as it disrupts gut physiology and risks visceral gout.
