Hover Fly (slightly 

 magnified). 



Hover Fly. 



Giub 2 days oLd, devouring 

 a green fly much larger than 

 itself (magnilied 4 times). 



The fuU-giown grub cap- 

 tures a green fly on a pea 

 flower and — 



lifting it clear of the leaf — 



extends its body in a rigid 

 attitude and sncks the juices 

 of its prey. 



The hover fly just 

 emerged from its chrysalis, 

 the broken skin of which 

 is seen above.
