All of these houseplant and insect visitor photos were taken in September 2017 - I'll make separate posts for October and November pictures!  The plants in question are (in order): Hoya carnosa compacta, Mammillaria schiedeana, Parodia mairanana, Stapelia gettlleffii, Stapelia schinzii var. angolensis, Ariocarpus retusus var. furfuraceus, Gymnocalycium mihanovichii, Gymnocalycium ragonesei, and Dracaena marginata tricolor.  The insects in question are respectively a Redfooted Cannibal Fly (Promachus rufipes), a bumblebee pollinating the Hoya carnosa compacta flowers, a tan moth, and a praying mantis I named Vladimir (after Saint Vladimir) on a Dracaena marginata tricolor.  You can click on any of the thumbnails to see a larger version of the photo.
