Hi All,                        Aug 9, 2013
    I don't want to sound like a wet blanket but one should be aware =
that both Bug Guide and images have limits; the truism that a picture is =
worth a thousand words nonwithstanding.

    This Feb., I wondered what the oval 'shelters', that are made of =
shredded White Pine inner bark, in which I have found Pytho americanus =
Kirby are called and whether they are made by the larval or adult stage. =
So I  Googled Pytho and was pointed to a Bug Guide image of Pytho =
americanus Kirby that did not remotely resemble the genuine article.
=20
    Recently I failed to ID an image of a very common fern that I have =
know for 75 years and which I see just about everywhere in my woodlot =
during the growing season. It was a perfectly good image but it looked =
too green, too firm and too regular to be what it was.=20

    Nothing beats first-hand contact with the organism by unaided eye, =
feel, hand lens or microscope as applicable.=20

Yt, Dave Webster, Kentville

  Great photo, Nancy.

  Your i.d. seems reasonable but take a look at Hesperophylax =
designatus.

  Caddisflies must be difficult  for even the experts to identify.
