Caterpillar setup for the mangrove skipper (Phocides pigmalion okeechobee). Place Rhizophora mangle propagules in cup and seal off opening with a lid with a slit. Place fish fertilizer along with water in a semi-closed terrarium so that the red mangroves will grow. Plants grow well in a semi-closed terrarium setup with glass on top to create humidity. Host propagules can be purchased from Mighty Mangroves.
