Strict insectivores — they eat only insects, never plant matter of any kind.
Leopard geckos cannot digest plant matter at all. All insects must be gut-loaded (fed nutritious food for 24h before feeding) and dusted with calcium + vitamin D3. Variety is important — don't rely on just one insect type. Feed juveniles daily, adults every other day.
