Whenever I feed my cephalotus<span style='color:red'>[Edit: I'm assuming you mean Cephalotus follicularis, species names have two parts, first part=genus, always capitalized, second part=specific epithet, always lower case; together they comprise the species name]</span>, the pitchers develope some kind of mold and shrivel up. I have tried feeding them crickets, ladybugs, and milk. Could this be from stagnant air? Or bad food maybe?
