5/30/2024      Fieldtrip report: Col. Devin Trail, 25 May by Marceline VandeWater

The weather was very pleasant but could have been a bit sunnier this year! 14 Participants started up the col. Devin Trail from Washington Park Trailhead and in the beginning the butterflying was really slow. In the end though: 24 species of butterflies were seen within the group, with Western Pine Elfin and Morisson’s Skipper being the most special, but Zela Metalmark the photo-op favorite. Total list: Two-tailed Swallowtail (3), Checkered White (3), Dainty Sulphur (2), Orange Sulphur (4), Bramble Hairstreak (2), Marine Blue (6), Spring “Echo” Azure (6), Western Tailed-Blue (4), Gray Hairstreak (1), Western Pine-Elfin (1), Zela Metalmark (2), Northwestern “Atlantis” Fritillary (2), Mylitta Crescent (1), Common Buckeye (3), Red Admiral (1), Red-spotted Purple (2), Weidemeyer’s Admiral (1), Arizona Sister (3), Mourning Cloak (4), Funereal Duskywing (2), Silver-spotted Skipper (9), Northern Cloudywing (3), Morisson’s Skipper (1), Common Checkered Skipper (1).

3/30/2024      Status of Butterflies in the United States by John Wesley Powell Center

As part of a USFWS -USGS Powell Center funded Working Group, we evaluated trends in abundance for all butterfly species across the United States, using data from 35 monitoring programs. Almost a quarter of these species were declining at their range-wide continental scale and over half of the species declining in at least one USFWS region. Butterfly species are declining across all butterfly families and ecological traits provide little predictive power in explaining overall trends. However, almost a quarter of the species were increasing in at least one USFWS region. We discuss biases in these data with respect to likely drivers of butterfly declines, as well next steps for developing collaborative efforts across organizations to rebuild butterfly populations. read more »

3/18/2024      Fieldtrip report: Superstition Mountains, 16 March by Ron Rutowski

Twelve of us ventured up the Apache Trail on a day after substantial rain storms moved through central Arizona. The passage of the storm was evident in the visible dusting of snow on Four Peaks and the water flowing over the fords at Tortilla and Mesquite Creeks. No butterflies were seen on our first and brief stop at Tortilla Flat. We moved on to Mesquite Flat where we spent about an hour and saw just one American Snout, although the birding was good (Sage Thrasher, Costa’s Hummingbird, three species of Towhees, etc.). We moved on to the Fish Creek Vista where butterflying was more productive, especially on the hilltop beyond the end of the paved trail. There, we were especially pleased to find a Fulvia Checkerspot (pictured) among the hilltopping species. What started out as a slow day ended with some good sightings. Our list of butterflies for the day is short which is not surprising for a beautiful but cool spring day following a major storm: Pipevine Swallowtail, Gray Hairstreak, American Snout, California Patch, Fulvia Checkerspot, Painted Lady, Red Admiral, Meridian Duskywing. read more »
