In the wild......... insects, bugs and many other things are part of their diet yes.
However, our gliders are not in the wild they are in captivity. There for everything is different.
Climate is different, freedom to roam is different, the distance to find food is different, energy being used by the body is different ( 3 foot cage compared to a 100 foot tree ) , food availability to them is different in the wild food is seasonal... etc I could go on but I think you get the gist.
Insects in captivity are used primarily as treats and enrichment ( hunting instinct) They are NOT used a vital part of their diet by most people.
There was one lady that fed a diet as close to a wild gliders diet as she could. The gliders lived in a terrarium kind of enclosure where everything was natural. She fed live baby chicks, bugs and insects, gums etc... along with a "staple"
I get the concept, but it wasn't widely done by the community. Later on that owner learned that her feeding plan wasn't feasible for the average glider owner. By the time she modified the diet to be feasible and balances she pretty much ended up with bml
Her staple diet was public and can even be found in old archive threads on here, but what
wasn't public was all the other stuff she was feeding like live chicks and the complete list of insects bugs and gums she was also feeding. So anyone that was feeding her staple was feeding an incomplete diet.
My point is, if your going to use the classification of "wild" to support ONE food source out of many they have available in the wild, then you also have to understand the differences between "wild" and "exotic pets" and everything that entails, not just one part of it.
If you are interested in dietary needs of captive gliders, get more active in the diet study
There is a diet study in progress, you can contact Shelly to find out more and get resources for accurate research information.

Please do not feel mealies are a vital part of their diet in captivity. They are treats, the vital part of their diet is their staple which provides vitamins minerals protein etc... Vets are not dietitians they are vets and usually have limited knowledge on glider diets.
Some gliders don't even like mealies
shocking, but true. Younger gliders ( 8 months or younger ) usually don't want anything to do with mealies until they get a lil older.
Personally, I get mealies about once a month from a local pet store. My gliders that eat them get about 4 or 5 each, when I do nail trimmings sometimes more if it's a fast eating glider and I'm not done trimming lol. I trim nails about every other week or when needed. So, my gliders get mealies about every other week NOT daily. Mealies are actually pretty high in fat, and some of my gliders are um well lets say far from being petite lol
