Three cabbage whites seen in flight. Wild plum is usually in full bloom here on May 7. The flowering buds on wild plum shrubs I checked today (May 10) are barely swollen and not showing any white at all. Plant phenology is at least 8-10 days late this year. Ditto, I would presume, to see elfins and spring blues in full flight.

Mostly sunny, 80-97 degrees F. We walked 9 miles in barrens sites, all but one of which has Frosted Elfin records: Dike 17, North Brockway East, several in the Bauer-Brockway area, Stanton Road, west of Hunter Haven Road, and 1 other area. All of the Henry's Elfins were that were 0.05-0.5 miles west of Brockway Road in about 6 different survey units. Butterflies seemed to shut down activity before 1 pm, presumably due to dessication. We saw no butterflies in the last 2.4 miles of surveying, when we were in the best Frosted Elfin sites we tried today.

Eight of us spent 15 minutes scanning an acre of bearberry plants north of a two-track east-west "road" just to the north of Clemens Creek, but no Hoary Elfins were seen. This site has been a sure bet for Hoarys in years past. Two elfins were seen along the road; one was positively identified as a Henry's Elfin. Still early spring up there--buds on red oak scrub shrubs were just starting to swell.

Surveyed primarily along North Brockway service road (44.31749, -90.741182) and forest land north of Bauer Rd starting at the Bauer-Brockway Barrens project area sign (44.298493, -90.748186). Both Hoary Elfins were found in the latter location. Also carefully looked at patches of birdsfoot violet in areas to the west and south of the main parking area with hopes of finding a Cobweb Skipper, but none were found. We did not notice many lupine plants in that area, and none were flowering. Butterfly activity significantly decreased by the afternoon due to winds and overcast conditions. Also observed Northern Barrens and Oblique-lined Tiger Beetles.

Also saw the first tiger swallowtail of the year, but I didn't get a good enough look to be able to say whether it was a Canadian or an eastern.

Very few BFs on this windy day, but it's worth reminding everyone that this is MaxLilacs week at the Arboretum - absolutely worth visiting. Also a sandhill crane is nesting ten feet from the platform at Teal Pond - viewable through a window of the curtain.

Location: Barrens between Millston and Black River Falls
Jackson County

We walked 14 miles of barrens transects in most of the best Frosted Elfin sites in our Frosted Elfin long-term monitoring (mostly 28-35 year time series). Today probably ranks as about our 4th, 5th, 6th, or 7th highest Frosted Elfin day ever in Jackson, Wood, or Jackson + Wood Counties. Five of the 6 roadside ROW and pipeline ROW units along Stanton Creek Road had their highest Frosted Elfin counts ever. Also record-setting was the pipeline ROW diverging to the northwest parallel to an ATV trail about 0.5 mile north of Stanton Creek Road. We also surveyed 7 more miles of transects west of Hunter Haven Road in addition to the pipeline, and 10 survey units in the Bauer-Brockway Barrens area. We also saw at least one undentified elfin and 36 unidentified duskywings.

Sunny, windy and almost 70 degrees. While I was in the garden, I spotted this small individual flitting about. It landed first in the grass and then favored a sheltered flowerbed along my house. It didn't linger, just long enough for a side and top view. Lucky day, my first Elfin sighting ever.

This was my first walk about the prairie and was happy to find a variety of butterflies enjoying the prairie. I even found a half dozen Monarch eggs on young Common milkweed and one adult Monarch flying.

We walked transects in 3 areas: 0.5 miles in a super heavy litter grassland (no butterflies), 0.5 miles each for a total of one mile of roadside ROW (3 Cabbage Whites, 1 Mustard White, 1 Meadow Fritillary, and 2 Mourning Cloaks), and 0.5 miles in a grassland plot 70% mowed in late Summer 2021 (all the other butterflies listed, plus 6 unidentified whites).
