322 A YEAR OF COSTA RICAN NATURAL HISTORY 



Although the plants and animals of Cartago and the Ba- 

 nana River district are mostly different, correlated with the 

 differences in altitude and in temperature, there are many 

 species which are found in both places, such as the escobilla 

 {Sida rhombifolia) among plants, Anartia fatima, the most 

 common of Costa Rican butterflies, Pantala flavescens among 

 dragonffies, and among birds the tijo-tijo or garrapatero 

 and the black-headed (zopilote) and red-headed (zonchiche) 

 vultures. The water-hyacinth, so abundant in the West- 

 falia laguna, grew in a ditch in Cartago.
