Caloplaca (biatorina?) "Orange Rock Firedot Lichen"
National Bison Range, MT
June 8, 2014
Robert Niese
Caloplaca lichens are a relatively abundant, easily recognizable group of lichens here in the PNW. Most orange, crustose lichens growing on rocks in our area belong to this genus. Unfortunately, the genus is impossibly large and making species identifications may require a close analysis of spore morphology.

Robert Niese
This widespread member of the rose family is best known for its fruiting stage in which each flower transforms into a dense bunch of wispy, feather-like seeds earning it common names such as “Old Man’s Whiskers” and “Prairie Smoke."

Northwestern/American Crow (Corvus caurinus/brachyrhynchos) Corvidae
Cape Flattery, WA
August 19, 2014
Robert Niese
While, as a scientist, I seriously doubt the validity of the “Northwestern” distinction for our PNW crows, if there were ever a crow that could be called a “Northwest Crow” it would have to be one at Cape Flattery (the northwestern-most point in the contiguous US). Northwestern Crows are, however, likely a subspecies of the American Crow and can only be identified based on their range of occurrence, which undoubtedly overlap for most regions.
Ectoedemia sericopeza “Norway Maple Seedminer” Nepticulidae
Missoula, MT
September 25, 2014
Robert Niese
These teensy-tiny moths are rarely over 2mm in length and are among some of the smallest lepidopterans in the world. Their larvae, which are equally infinitesimal, feed exclusively on (and within!) the tissues of the Norway Maple (Acer platanoides), an introduced species which lines most of our streets here in Missoula.
Anthopleura elegantissima “Aggregating Anemone” Anthozoa
Olympic National Park, WA
June 1, 2013
Robert Niese
A very common intertidal resident here in the Puget Sound and on the open coast. If it’s big and green, it’s Anthopleura xanthogrammica. If it’s white and has very fine tentacles (usually subtidal, not intertidal) then it’s Metridium. Now you can identify 90% of the anemones you find in your backyard!
