Nice write up on them! And some nice pictures to go along with it.
Pros:
Since you are producing your own endless supply of feeders, you don't have to worry about hustling down to the petstore when you get off work to pick up more food or bug your parents to take you to the petstore for the fifth time this week. You also don't have to spend $$$ on gas driving there!
If you like to go fishing, free bait!
Robins, Bluebirds and various other bird species love mealworms and superworms both! Watch your backyard birdies enjoy a new treat!
On the Cons, I wouldn't really consider it a time consuming thing, more of a prolonged project than anything. They really don't take a lot of physical time, it just takes a period of time before they get up and going. But the upside to that is that once they are going, you won't have that worry anymore. Much like getting a colony of Dubia started for instance.
Under your morphing info, you mentioned separating them out, but don't specify that they should have no food or moisture when separated in order to stress them which forces the pupation. You note this in the cliff notes section, but not the morphing part. I would add that info to the morphing paragraph as well so people don't miss that part if they skip the last sections (which people do
).
Another idea, add a list of "Things Needed" of "Materials" towards the top. Reading the article, I find throughout that I need another container, and yet a third container and possibly even more depending on how often I move the beetles. A shopping list could be very handy there. Having a list upfront helps some people to get started a little more easily. Include things like food, moisture, containers, egg crates etc... Just a thought on that.
And one more thing, Non-medicated Chicken Egg Laying mash bought from a local feedstore should make a good substrate as well if you want to add it. I know lot's of people use it for supers and mealworms both and it is cheap stuff that works good.
Good work!
