FEEDING NOTES FOR CERTAIN ARTHROPODS 



Lucy W. Clausen, American Museum of Natural History 



THE following is a list of arthropods which have been kept for com- 

 paratively long periods of time in the cages containing live exhibits 

 in the Hall of Insect Life of the American Museum of Natural History, 

 together with the food organisms which have proven satisfactory for 

 each. 



ARACHNIDA 



Scorpions (several species) have been fed on mealworms and Oriental 



roaches. 



Tarantulas will eat roaches and mealworms. 



Pholcids (false Daddy-long-legs) eat Drosophila when small and 

 larger flies, such as Musca, when larger. 



The wolf spider, Lycosa carolinensis, has fed upon flies and meal- 

 worms. 



The garden spider, Aranea serkata, has been fed flies and grass- 

 hoppers. 



The crab spider, Olios sp., is fed mealworms. 



ORTHOPTERA 



Roaches (American, Oriental, and tropical) are fed sliced potato, 

 lettuce, bananas, bread, and a piece of bacon occasionally. They seem to 

 relish spinach when it is not given to them too often. 



Crickets are fed on apple, lettuce, and bread. 



Meadow grasshoppers are fed on apple and grass. 



Mantids (Chinese Mantis) eat Drosophila when small. When adult 

 they eat houseflies and mealworms. The latter should be dangled before 

 them on a thread to attract their attention. 



COLEOPTERA 



Tiger beetles (Cicindela sexgutata, C. dor salts, etc.) have been fed 

 on mealworms cut in sections, and on apple. 



Caterpillar hunters (Calosoma calidum and C. scrutator) have been 

 fed on mealworms and apples with banana occasionally. 



The ground beetle, Harpalus caliginosus, has been fed mealworms and 

 apple. 



Dytiscus eats small mealworms which are dropped into the aquarium. 



Mealworms (Tenebrionidae) are grown in bran with a slice of potato 

 added every other day. 



The red rust flour beetle (Tribolium jerrugineum) grows well in whole
