WILDFLONER PHOTOS WANTED by Katherine Clough 
     
    
   
   
    
     Geoff Hogan and I are preparing a book on familiar wildflowers of Prince 
     
     Edward Island. It will be published next spring by Ragweed Press and will be 
     
     the third volume in the Island Pathways series. Many of you are already 
     
     familiar with Familiar Birds of P.E.I., the bird book written by Geoff and 
     
     published this spring. we are looking for high quality photos of the species we 
     
     have selected for the new book and we therefore invite you to submit any photos 
     
     which may be suitable for inclusion. If you are interested in participating in 
     
     this project please give me a call at 566-4961, preferably between 7 p.m. and 9 
     
     p.m., and I will be pleased to give you a list of the species we are looking 
     
     for. If any of your work is selected you will receive a copy of the book and 
     
     $10 for each photo appearing in the book. 
     
    
   
   
    
     WHALE DISCOVERED adapted ‘rom Goewatch, Canadian Geographic Aug/Sep 91 
     
    
   
   
    
     The immensity of our oceans was once 
     
     again brought home when an American and two 
     
     Peruvian scientists identified a new 
     
     species of toothed whale, Mesoplodon 
     
     peruvianus. This 3.5 meter ong, dolphin 
     
     shaped whale is the first new whale 
     
     discovery in 28 years. This whale is 
     
     related to beaked whales such as Cuvier's 
     
    
   
   
    
     Beaked Whale which has been seen in 
     
     Canadian waters off the Atlantic and Pacific coasts. 
     
    
   
   
    
       
     
    
   
   
    
     SANFLIES 
     
    
   
   
    
     These non-stinging wasps use a saw-like apparatus on the tip of their 
     
     abdomen to cut plant tissue to allow the deposition of eggs into the slits 
     
     created in needles and leaves. There are many species of sawflies in North 
     
     America with approximately 100 species feeding on conifer foliage in their 
     
     larval stage. Depending of the species, some feed only on old leaves while 
     
     others utilize only new leaves. Some species occur only in the spring while 
     
     others occur in the summer and still others throughout the growing season. The 
     
     larvae of typical defoliator sawflies looks like a caterpillar but can be 
     
     identified by the more than 5 pairs of prolegs on the abdomen. Depending on the 
     
     species they may be defoliators, leaf rollers, webformers, skeletonizers, leaf 
     
     miners, bud miners, stem borers, or gall makers. 
     
    

    
     The yellowheaded spruce sawfly feeds primarily on the new growth of a 
     
     variety of spruces, preferring young, open grown trees. The insect overwinters 
     
     in the ground as a larval stage within a dark brown cocoon encrusted in earth. 
     
     Pupation occurs when the ground warms and adults, about 12 mm. long, emerge in 
     
     May or June. The female lays its eggs singly near the base of the needle and 
     
     the eggs hatch 7 to 14 days later. The larvae reaches its full growth of about 
     
     20 mm. in mid-July and then drops to the ground where it crawls into the ground 
     
     and spins its cocoon.
