The Tachina Flies 



This is one of the most beneficial fam- 

 ilies of insects, because of the parasitic 

 habits of the larvae upon destructive 

 caterpillars, grasshoppers, bugs, beetles, 

 saw flies, etc. 



The adults are little larger than house 

 flies, being striped and grayish in color 

 with hairy bodies. They are only active 

 on warm days. The eggs are usually 

 white and stuck to the living larvae upon 

 which the coming maggot is to feed. Upon 

 hatching the larvae bore through the

skin of the host, nourishing themselves 

 throughout their development upon the 

 internal tissues, avoiding the destruction 

 of the vital organs until ready to pupate. 

 When the host is destroyed they leave 

 the old carcass and form hard brown 



puparia near the surface of the ground. 

 The adults issue from these in a very 

 short time. Breeding is rapid, there be- 

 ing several generations each year.

Viceroy Butterfly 



Limenitis archippus 

 Occasionally the larva of the viceroy 

 butterfly is found feeding on plum leaves, 

 though its normal food is the willow. 

 The larva occurs from the latter part of 

 September until the leaves drop. This 

 species is not apt to become sufficiently 

 injurious to require special attention. 

 Hand-picking and spraying with poison 

 can be resorted to if necessary. The 

 hibernating larvae are easily discovered 

 after the leaves drop and can be collect- 

 ed by hand and burned.

The fruit of the pomegranate is about 

 the size of an orange and is fllled with a

 by a juicy, acid pulp, greatly prized as a 

 cooling drink. 



Pomegranates may be grown in parts 

 of Florida, Alabama, Mississippi, Louis- 

 iana, Arkansas and Texas, where the 

 climate is not too cold. 



The following varieties are recom- 

 mended by the American Pomological 

 Society for culture in the above states: 

 Acid, Dwarf, Sweet and Violet.
