Yes, that particular care sheet was written by Evan Ngo who raised and sold mantids for about three years before giving up the hobby or at least stopped selling, but his site has been kept up and has some useful info and great pix in it.
When we keep mantids in captivity, we tend to consult our own convenience in the live foods that we give them. Many mantids, particularly those that are "camouflaged" are ambush predators and tend to eat only what flies, crawls or hops into their range, so they are unlikely to eat a number of insects routinely offered by mantis keepers, such as meal worms, cockroaches, orb spiders and the occasional goldfish that finds its way onto You Tube.
Crickets are particularly useful for someone with only a few mantids, since they can be purchased, like meal worms, in small numbers at a local pet store and kept in a shoe box (you can find a lot information about keeping and feeding crickets, sometimes mutually contradictory, by using this forum's search engine).
And as the saying goes, "your experience may vary." Hibiscusmile, who was an experienced and successful breeder when I bought my first mantids from her, mentions the dangers of feeding bees and wasps unless they have been mutilated, and Evan, in another care sheet warns never to feed them, but a friend and I (Hi, Mija!) routinely feed "undoctored" bees and wasps to mantids big enough to take them, and have never experienced any problems.
And while you are getting all this excellent advice
. what are you feeding your P. aeruginosa?
