The WORST time for a filter to bypass is during initial start up when there are potentially tons of metal shavings in the engine. On a flat-cam engine, I use assembly lube on the cam lobes, lifter bases, pushrod ends, and rocker arm tips. On a roller cam engine, I skip the lifters and lobes.
Pictures Below â. Hellgrammites are the vicious larvae of the Dobsonflies, some of the only trout stream insects which pose a biting threat to the angler. The pincers of the adult are even more frightening that the larva's, and they're aggressive enough to use them once in a while. This family's life cycle does not create good dry fly opportunities, but the larvae may be eaten by trout year-round. They are a secret told only by stomach samples of well-fed trout.
A young hellbender in Western Pennsylvania was evaluated by a team of Clarion University researchers this summer.

If the name is any indication, the large aquatic amphibian is not what you'd call attractive.
