  • Stink Bug feeds on an Alder Cone shows one inserting its "beak" into the cone and sucking up the nutrients.
  • How they do this is quite fascinating. For information about this:
  • From Stephen A. Marshalls book on “Insects Their Natural History and Diversity”:

  • Stink Bugs and other Hemipteroids – are equipped with syringe-like beaks used to suck the liquefied contents out of other organisms (and plants).
  • This segmented beak is the lower lip (labium), which is extended to form a long, trough or gutter-like structure.
  • These mouthparts form four narrow blades (stylets) that fit into the long, sheath-like lower lip.
  • One pair of blades (mandibles) is for cutting, and the other pair (maxillae) is for spitting and sucking.
  • The maxillae combine to make a tube with two channels, one for sucking food up, and other for spitting saliva back into the food.
  • The slender, syringe-like stylets leave the bug’s labial sheath when the mandibles and maxillae slide against each other to penetrate prey or plant tissue.
  • The labium is sometimes bent back as the stylets snake their way into the host.
  • What are the Sea Lions Eating shows sea lions tossing about their prey.
  • They do this to tear their prey apart so they can swallow these pieces whole. 
  • Their teeth are not adapted for chewing.
  • This appears to be either a flatfish or possibly a skate. 
  • The Hemlock Sawfly is a series of videos that covers most of the habits of these insects and their relationship with western hemlock trees in Southeast Alaska.
  • For good information on their status in 2019 look at

  • Beavers Really Like Cottonwood Trees is a video I have been trying to get for several years. Finally was able to capture a beaver chewing on a tree. Hopefully will eventually get the tree falling.
  • They seem to do this mostly at night so it required setting a game cam to come on when they were active.
  • The video is set up without narration so someone could present it to others, such as students, and ask them what they thought the beavers were doing.
  • For information about beavers look at  Beavers by the Mendenhall Glacier in Juneau, Alaska
  • Beaver working on a Cottonwood Tree out of water shows a beaver eating some of the bark and chewing the tree. It also shows the beaver grooming and digging in the ground looking for some of the bark to eat. 
  • The tree eventually slide downward but did not fall. The beaver started working on another place just above the old one.
