So many of the insects are tiny, almost 
microscopic creatures, and so many of 
them perform their characteristic capers 
in inaccessible places, that the writer con¬ 
structed a laboratory for the special pur¬ 
pose of recording habits on motion picture 
film. By these methods students are en¬ 
abled to see habits the greater number of 
them would never in any other way ob¬ 
serve. Not one child in a million has seen 
the katy-did singing, the praying mantis 
rear in frightful pose, grasp and devour 
a fly, the toilette of a gaudy grasshopper 
as she carefully brushes pollen rust from 
her face, or the wolf spider, magnified 
ten thousand areas, carrying her family 
of hundreds of babies piled upon her back, 
and presenting an indescribable spectacle. 
It is not so difficult to obtain motion 
pictures of insects eating, as these crea¬ 
tures are ever hungry and persist in satis¬ 
fying their appetites even under greatly 
disturbed conditions, but to obtain scenes 
of nervous spiders caring for their young 
and to show insects singing—that is a dif¬ 
ferent matter. To induce the spiders to 
spin nurseries it was necessary to build 
special cases, painted black inside, make 
the spider feel at home by keeping her 
quiet for some time, feeding her and giv¬ 
ing her water, when she usually hatched 
her young, spun her nursery and stood 
guard over it. Then the case was placed 
upon the photographic table, the motion 
pictures’ camera adjusted, and a cruel deed 
performed. The photographer destroyed 
the silken nursery and removed the tan¬ 
gled ruin while the baby spiders ran fran¬ 
tically about their distracted mother, who 
immediately started the construction of a 
new and generally more elaborated nur¬ 
sery, and while she was doing this and 
her infants were being reinstalled, the 
camera was steadily clicking away to tell 
the story lated on the projecting screen. 
To photograph the katy-did singing by 
its scraping the wings was a difficult mat¬ 
ter. This insect sings only at night. A 
light of any kind will stop it. Yet to pho¬ 
tograph a singing specimen at night meant 
that a stream of powerful electric light 
must be turned upon the songster. The 
deed was done in a grove of young oaks 
close to the motion picture studio. Sev¬ 
eral dozen katy-dids were placed in the 
trees and the camera — on a high tripod — 
focused on the vegetation of a tree in the 
center of the grove. The instrument, with 
special long focus lens, was to record the 
movements of a single insect that watched 
all proceedings, but remained silent owing 
to our close arrangements with the ma¬ 
chines. The camera was then belted to a 
small motor so that no operator would 
stand by the instrument to disturb the in¬ 
sect. A searchlight such as is used in the 
navy was then trained on the single tree, 
in which reposed the actor, the powerful 
rays making photography possible. With 
the remainder of the grove in darkness 
the decoy katy-dids sang vigorously. _ In
