Darwin (1877) noted that the ability of orchid flowers to set fruit correlated positively with pollinator activity but pollinator activity was influenced by environmental changes. The authors of this chapter addressed the current literature on how climate changes influence the activity and seasonality of insects and flowering plants. A three year field study was conducted at a reserve in southwestern China on flowering seasons in 54 orchid species. A long, cold winter in 2008 delayed flower initiation in approximately half the species observed by five days or more. In contrast, a drought in 2010 delayed flowering by five days in three terrestrial orchid species belonging to the genus Geodorum.
