II. FIELD AND SHRUB STRATUM. 



The young trees go to make up a considerable portion of this 

 stratum and together with the numerous shrubs and herbs 

 support large numbers of insects. The tree- and leaf-hoppers 

 are particularly abundant. 



Lepidopterous larvae are also very abundant, some tying 

 and rolling leaves, others mining them. The larvae of Gelechia 

 cercerisella, a particularly interesting species, fold the leaves 

 of young redbud. The leaves of the basswood are often made 

 unsightly by the work of Pantagrapha limnata. (Fig. 11).

Nat. size. 



- The pretty and strikingly-colored syrphid, Milesia vir- 

 giniensis, is found buzzing around fallen logs and is taken 

 occasionally at flowers. Many beetles, as Coptocyda clavata 

 and members of the genus Lema are found feeding on the low 

 herbage. (Fig. 12). 



Grasshoppers are found in this stratum, but are not par- 

 ticularly numerous. The locustids greatly outnumber the 

 acridiids. In low marshy places at the edge of hammocks are 

 found the grouse-locusts, Tettigidea lateralis lateralis and 

 Neotettix coarctatiis. 



The blue chrysomelid, Porphyraspis cyanea, (Fig. 13), is 

 typical of the saw-palmetto upon which host alone it feeds. 

 A small tineid, Ilomaledra sabalella, also feeds on the foliage 

 of this^plant.
