STATE BOARD OF AGRICULTURE 



INSECT AND ANIMAL LIFE 



ON THE UPPER PENINSULA EXPERIMENT 

 STATION.

INTRODUCTION. 



Durint? the latter part of Aujrust the writer, in company witli Professor Wheeler, 

 visited the State Sub-station at Chatham, remaining there about twelve clays. After- 

 ward a visit was made to Beaver Island, in Lake Michigan. During all the time the 

 object of the writer was to obtain specimens of as many forms of animal life as 

 possible, with special reference to economic species. The following brief report 

 deals mainly with the life at Chatham, although the list of shells and spiders includes 

 those at Beaver Island as well. 



The time of the year was not an ideal one for collecting, although for economic 

 work it was perhaps as good as any. Considerable time was consumed in preparing 

 specimens, t)oth vertebrate and insect, and in taking photographs; and, of the 

 material collected, it is at present impossible to include a considerable part, as a 

 number of the insects are still in the breeding cages, and very many more will have to 

 be sent to specialists for identification. 



The writer wishes to extend his thanks to Dr. Bryant Walker, of Detroit, who has 

 kindly determined the molluscs; to Mr. Nathan Banks, of the Division of Entomology 

 at Washington, who did the same for the spider, the Neuroptera and 

 the Trichoptera; to Professor W. S. Blatchley, State Geologist of Indiana, for deter- 

 mining one of the grasshoppers, credit for which is given in the text: to Mr. Matt 

 Crosby for the privilege of examining his collection, made at Chatham during the 

 past season, insects listed from his collection being marked with his name; and to Mr. 

 Leo Geismar for aid and kindness shown in many ways. 



TREE-HOPPERS AND LEAF-BUGS. 

 {Jassidae and Capsidae.) 



Many species of small tree-hoppers, leaf-bugs and other sucking insects were found 

 in the regions visited. It will not be necessary to go into exact details in discussing 

 them, since the same general remedies serve against almost all of them. They are 

 very small insects, usually elongated and often green or pale in color, though some of 



Hollyhock bug (Orthotylus delicaUts), from Cook and Davis, Bull. 76 Mich. Exp. Station.
