THE COCCID^ OF AUDUBON PARK, NEW ORLEANS, LA.i

Entomology 



Audubon Park, New Orleans, is a particularly favorable locality 

 for the development of plant and insect life. The climatic conditions 

 are such that plants seem to thrive with equal facility whether they 

 are transported from regions far to the north of Louisiana, or from as 

 far to the south. Scattered through the park may be found repre- 

 sentatives of almost all the common ornamental plants of the Northern 

 States, while flourishing side by side with them can be seen hundreds 

 of plants representing the native semi-hardy flora and plants imported 

 from the semi-tropical regions of Mexico and Cuba. In one corner of 

 the park may be found the huge Horticultural Hall, a relic of the 

 Cotton Centennial Exposition of 1884. In this hall hundreds of 

 species of tropical plants are found, which are carried through the 

 comparative coldness of the Louisiana winters by means of artificial 

 heat. Altogether, it is doubtful if many places can be mentioned 

 where the observer is confronted by such a luxuriant and varied array 

 of flora in a circumscribed area as can be found in this piece of land of 

 less than 300 acres within the city of New Orleans. 



The same conditions which make possible this diversity of plant 

 growth, also make this spot an ideal one for insect development. 

 'With the exception of a few weeks of moderately cool weather in the 

 winter, insect growth and multiplication is practically continuous the
