Can leopard gecko eat mealworm pupa morphing into s beetle?

Mealworm Pupa or what breeders reffer to as "aliens" are a very tough exo skeleton insect. During this stage the worms are protected by their outter shell and this makes them very difficult to digest and swollow. Most leopard geckos would not eat them as they do not move enough for the insect to grasp the geckos attention. I do not reccomend using mealworm pupa "aliens" as feeders.
