Pretty much everybody on the planet has had an unusual year this 2020.  For us here in Oregon\u2019s Outback, life has been close to normal except that our pattern of paid work has changed and I no longer have a busy travel schedule. Limitations on tourist travel also affected our camping and collecting year. But overall, living on the outskirts of a tiny town have allowed us to keep up a normal habit of outdoor activities and explorations, albeit closer to home than normal.<\/p>\n\n\n\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Collecting disruptions started early, however, because I had planned to spend a couple weeks of April in the hills near the ocean in SW Oregon.\u00a0 Then lockdowns interfered and the entire trip was canceled.\u00a0 Oddly, 2020 also brought a very poor year for my beloved aphids in SE Oregon.\u00a0 Many species that are normally common almost everywhere I go were rare or impossible to find this year.\u00a0 In fact, sagebrush produced almost no aphids this year until September. Instead, sagebrush was beset by psyllids, leafhoppers, and mirids. I\u2019ve seen this shift away from aphid domination of sagebrush before. We need another graduate student to figure out the ecology behind this phenomenon!<\/p>\n\n\n\n

            Slow collecting and no work travel left me with more time to work on a major manuscript that I\u2019d been planning for this year \u2013 the aphids of Holodiscus<\/em>. This paper includes information I\u2019ve been gathering since the early 1990s. I\u2019ll have to try to share more details once it is published.<\/p>\n\n\n\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Despite the roadblocks, I made some good progress on several field research efforts this year.<\/p>\n\n\n\n

Apparently undescribed species of Aphis<\/em>.<\/span><\/p>\n\n\n\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 In our local forests I have been pursuing a handful of Aphis<\/em> species that seem to be heretofore unknown. One of them lives on various Umbelliferae from our valley floors (about 1200 m elevation) to our mountain streams and peaks above 2000 meters. It has been hard to capture photos of this species because of its very active habit.\u00a0 But, 2020 gave me a good photo op.<\/p>\n\n\n\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Another Aphis<\/em> I\u2019ve been after lives on Hackelia<\/em> (Boraginaceae) at mid to high elevations. It is all black and closely resembles one of the Aphis<\/em> found on Veratrum<\/em> (Liliaceae) and one of the species on Valeriana<\/em>. In life these black Aphis<\/em> make me think of the group of species that live on Senecio<\/em> and relatives, but less so when mounted on slides.<\/p>\n\n\n\n

The more I look at this species, with its strange body shape and long apical rostral segment, I wonder if it is related to the subgenus Zyxaphis<\/em> that feeds on sagebrushes and rabbit brushes.<\/p>\n\n\n\n

Important Macrosiphum<\/em> finds<\/span><\/p>\n\n\n\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Early in the season (June) I took a day off from work and collected in our nearby Fremont National Forest.\u00a0 Near the end of the day I found the long-elusive fundatrix of my recently described species Macrosiphum glawatz<\/em> on Potentilla gracilis<\/em>. It was living on a nice green plant that was actually rooted in a disused roadway. As with several of my favorite species in this genus, the fundatrix of M. glawatz<\/em> is almost indistinguishable morphologically from regular early season viviparae. On that same trip I was able to find the fundatrix of the undescribed species that lives on Lonicera cauriana<\/em>.<\/p>\n\n\n\n

There, I was lucky to find many good specimens of the undescribed Macrosiphum<\/em> that lives on the sticky forest-inhabiting Silene<\/em> that grows on certain soil types from the Cascade Mountains east and south. Most important was a presence of the fundatrix stage.<\/p>\n\n\n\n

That trip also started a string of finds of the undescribed species that lives on grouse whortleberry (Vaccinium scoparium<\/em>).<\/p>\n\n\n\n

Pseudoepameibaphis<\/em> \u2013 my second favorite genus (for the moment)<\/span><\/p>\n\n\n\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Having finished one big paper this year, I am considering making my next one a thorough coverage of what is known about a sagebrush-inhabiting genus called Pseudoepameibaphis.<\/em> I\u2019ve got lots of new information, hypotheses about host-specificity, and at least two new species.\u00a0 The most exciting new species is one that looks much like a little beetle \u2013 it is black and its dorsum is hard and sometimes brittle like a beetle. It seems to live almost exclusively at or near the top of mountain peaks on the category of Artemisia tridentata<\/em> called mountain sage, and sometimes shares plants with a more typical pale member of Pseudoepameibaphis<\/em>. On that special day in June I was able to retrace my steps from a couple years before and find this aphid living adjacent to a particular burned and fallen tree on Winter Rim. Many other plants in the area sampled, and only on this plant did this aphid species live.\u00a0 Later in the season I found it on a few plants along a high elevation stream in the Warner Mountains.<\/p>\n\n\n\n
