The Meyers-Deats Conservatory features bromeliad, orchid, and cactus collections and tropical houseplants. Bromeliad beetles ("Metamasius callizona") destroy bromeliads and the ecosystems they host. It inhabits a type of water-collecting epiphytic bromeliad found at these elevations. Occasionally grazing on bromeliad roots, it also eats acacia pods and fallen cactus flowers. Puya chilensis is a terrestrial bromeliad originating from the arid hillsides of Chile. Alcantarea imperialis is a species of bromeliad in the genus "Alcantarea". Tillandsioideae is a subfamily of plants in the bromeliad family Bromeliaceae. This frog inhabits the tank of the giant bromeliad "Brocchinia micrantha". These bromeliad invertebrates benefit their hosts by increasing nitrogen uptake into the plant. Aechmea gamosepala is a bromeliad endemic to southern Brazil. Neoregelia carolinae or Blushing Bromeliad is a species in the genus "Neoregelia". "Wittrockia" is large among bromeliad genera, producing long, glossy leaves armed with sharp spines. Examples include a tadpole preserved in amber after falling from a bromeliad. The queen of the Andes is the largest species of bromeliad. Only one bromeliad, the pineapple ("Ananas comosus"), is a commercially important food crop.
