Tachinidae 



The Tachinids are, insofar as known, all parasitic on other 

 insects, and besides being most beneficial in keeping the 

 insect life in balance, are among the most interesting to collect 

 and study. Wliile, of course, the usual methods of sweeping, 

 etc. are used in this family, I particularly recommend breed- 

 ing, for in that w^ay one gets perfect specimens and complete 

 records.
