the first place, and it is often eaten by species in confinement in preference 

 to the natural food-plant. Hawthorn, Lotus (trefoil), and Glechoma (ground 

 ivy), sallow, and sloe are also useful. For the Noctuse the following plants 

 have been found acceptable sallow, birch, plum, hawthorn, plantain, dock, 

 dandelion, lettuce, clover, borage, goosefoot. When the food-plant is 

 known, but cannot be procured, plants of the same natural order may be 

 pretty safely substituted, and many will eat hawthorn or knotgrass when 

 their natural food is not within reach. It is here, as in working out other 

 branches of entomology, that a knowledge of botany is desirable ; and the 

 collector should not fail to make it his business to learn "all about " plants, 

 as well -as his favourite insects. If he does not, he will constantly find his 

 progress impeded, and his ignorance upbraiding him. He should do this 

 not by merely going through a cramming course at a Science School, how- 

 ever useful that may be as a groundwork for technical knowledge, but by 

 super-adding to it the work of field botany, and mastering the mysteries of 

 classification, and the best systems of natural arrangement.
