HOSTS 



The Membracidae have shown themselves to be excellent botanists 

 and in most cases confine themselves to very definite host plants both 

 for feeding and for oviposition. In many cases the association between 

 the membracid and the host is so characteristic that a knowledge of the 

 one is sufficient for recognition of the other. This is particularly true for 

 such species as Telamona ampelopsidis, which not only confine themselves 

 to a single host but are the only species ever found on the host. A 

 large number of species of the family have been named to indicate 

 such associations, and the local forms with such specific names as querci, 

 castaneae, crataegi, ampelopsidis, and the Uke, are representative of such 

 species. 



The host plants concerned may be divided into four rather well-defined 

 groups of plants. The most important of these groups is represented by 

 the Amentiferae, including such nut-bearing trees as oak, hickory, butter- 

 nut, chestnut, beech, and hazelnut; of hardly less importance are the 

 legumes, of which the local forms of locust, sweet clover, alfalfa, and red 

 clover are favorite hosts for many species of membracids; the Rosaceae 

 in general, but particularly apple, pear, berries, and cultivated i«3ses, 

 represent the third group; while the fourth includes a large number of 

 succulent composites such as annual asters, sunflower, daisy, joe-pye weed 

 and thistle. Practically every plant that has been recorded as a host 

 plant for any species of Membracidae may be included in one of these 

 four groups.
