Figure 25. — Young Tobacco Worm, a 
Caterpillar. 
One of its insect enemies has laid 
eggs in its body which have hatched 
into caterpillars. These caterpillars in 
turn have fed upon the tobacco worm 
until it was time for them to pupate. 
They then ate their way out of the body 
of their host and spun their cocoons 
which are attached to the surface of the 
body. What will happen to the tobacco 
worm ? 
Figure 27. — Larvae of Leaf Miner at 
Work in Elm Leaf. 
The larvae are between the upper and 
lower transparent epidermis of the leaf. 
They have eaten all the inner layers of 
the leaf, see Figure 263. 
Figure 26. — One of the Swallowtail 
Butterflies (not common). 
Notice that the tongue is extended by 
means of loop of wire. This gives an idea 
of the length of the tongue in comparison 
with the body. This tongue enables the 
butterfly to gather nectar from flowers 
with long nectar spurs.
