Scott and Ann Swengel

Location: Bogs near Amnicon Lake
Douglas County

80+ degrees F. We surveyed Lyman Lake Bog and its roadside, Bear Lake and North Bear Lake Bogs, and Milchesky Road 1.75 Bog hoping to see Freija Fritillaries and Red-disked Alpines. The Mourning Cloak was near, but not on, a bog. Because we found so few butterflies we didn't survey the last 4 bogs on this route.

I had thought that these would be Mustard Whites but didn't have a camera nor binoculars when I first saw them, After counting 15 white butterflies I went back and took these photos of one. Almost all appeared to be laying eggs on Broad-leaved Toothwort (Cardamine diphylla) and I was only able to catch up to this one, which was more my speed. The next day I was able to see both Mustard White and Cabbage White so I don't know the exact numbers.

Four patches adjoining County Highway X. All have past Frosted Elfin records but the most recent was in 2010. We monitor these sites long-term for all 5 elfins and other butterflies. We also saw 7 unidentified duskywings. The Meadow Fritillary count is higher than usual for these sites.

Temperature was a cool 48-52 degrees for the couple hours (3-5PM) spent on Crex. The few butterflies seen were in protected areas, e.g., north roadside of Klotz Rd. just east of James Rd., with an oak forest to the north to stop the wind. The Silvery Blue and Duskywing were seen here. Four Olympia Marbles were on the south-facing slope below Crex Ridge Road.

8.25 hours. We also saw 1 unidentified blue and 203 unidentified duskywings. Most sites have past Frosted Elfin records and are sites in our long-term monitoring for Frosted or other elfins. We also chose some sites to survey especially for Cobweb Skippers. Sites were Dike 17, North Brockway East, Cemetery Road near Lichtner (or Seils Road), Bauer-Brockway Complex, Stanton Road, and west of Hunter Haven Road. Frosted Elfins were found in 9 different units, including 2 within 1/2 mile west of Brockway Road 2 along Stanton Road and the pipeline ROW next to it, and 5 west of Hunter Haven. Most of the Henry's Elfins were within 1/2 mile west and 1/2 mile south of the Bauer Road/Brockway Road junction.

Bear Lake and North Bear Lake Bogs along County Hwy A, Milchesky Road 1.15 Bog and roadside, Milchesky Road 1.75 Bog, and Lyman Lake Bog and roadside. North Bear and Miclhesky 1.15 were by far the least productive of the bogs for Freija Fritillary sightings today, but we saw 1 Red-disked Alpine on North Bear. Mostly sunny, except for when we surveyed the long-term best bog (Milchesky 1.75) for Freijas and Red-disked Alpines. On Milchesky 1.75 we saw 20 times as many butterflies per minute when the sun was shining or partly shining as when it wasn't shining. For us, seeing one Freija Fritillary (usually we see zero in that unit) on our Lyman Lake bog roadside survey was unusual.

Also had a few American Emeralds and a gazzilion Hudsonian Whiteface, along with a few Beaverpond Baskettails, a Common Whitetail and a few Common Green-Darners.

Gravel roads at Crex were dry, not attracting any butterflies. Animal scat at Reed Lake certainly was, however. Numerous (over 50) flighty duskywing skippers went unidentified. I have never seen as many Henry's Elfins in a day before. Sites where Eastern Pine and Brown Elfins were seen in years past were barren. I checked extensive stands of bearberry north of Clemens Creek Firebreak on the Namekagon Barrens but saw no Hoary Elfins. Mostly sunny, temperature in low 60s.

We also saw an unidentified white (we think Pieris sp.) flying over the bog west of FR 137 1.2 miles south of Highway 70. South of FR 136 we sat for 42 minutes waiting for the sun to come out in the best opening we know of for Red-disked Alpines (RDAs) and Freija Fritillaries. When the sun came out we saw 12 RDAs and 15 Freijas in the next 14 minutes.

Scott and Ann Swengel

Location: 6 bogs
Forest County

In the Nicolet NF east of Three Lakes we surveyed bogs along Forest Road 2182 that were north of Wolf Lake (best one for early spring specialists), east of Wolf Lake, and 1.4 miles east of 2182's jct. with FR 2176. Near there in the Nicolet NF we surveyed a bog west of the southern part of FR 2414. We also surveyed 2 bogs outside the Nicolet NF. Mostly sunny, 59-71 degrees F. Brown Elfins are at a very low point in their 4-5 year bog population cycle across all of the bogs we've seen this year: see Figure 2 of Swengel and Swengel 2015. Assessing abundance patterns of specialized bog butterflies over 12 years in northern Wisconsin USA. Journal of Insect Conservation 19:293-304. Full-text is open access at the journal website or at Ann or Scott's ResearchGate pages. The Freija Fritillary total was lower than usual. Nicolet NF bogs are the wettest in the last 20 years. One bog we stopped surveying in 2019 would be a swimming pool across our entire route now. East Wolf was so deep that no boots would be high enough; Ann took off her water-filled boots out in the bog and the mud suction was so strong that her shoes came off too--she surveyed in her socks.

2 patches in powerline and ATV ROW east of County I that are 7-8 miles south of U.S. Hwy 8. 65% sunshine, 72-76 degrees F. Usually the more southerly patch here produces more Chryxus Arctics than the 2 today (we saw zero on the northerly patch), but we can't tell much about where the species is in its flight based on seeing it only on one day this year. We also saw one unidentified duskywing.

Dean Hansen

Location: Crex Meadows, Namekagon Barrens SWAs
Burnett County

14th annual Crex-to-the-Barrens butterfly trek had nine guests. The rain that had brought butterflies to damp road gravel for Terry Mortier on Saturday had dried enough by Sunday that we did not see the swallowtail, Gorgones, or Roadside Skipper that he had seen. Olympia Marbles were present at nearly every stop. Duskywings were plentiful, but flighty and hard to ID. I did capture and check two small males for the diagnostic hair plume (or not) on the hind tibia; one had it, one did not, so that's one Dreamy and one Sleepy Duskywing positively ID'd. Nice to see that the past few days of warm weather had brought out Eastern Pine Elfins on Springbrook Trail, Brown Elfins on a bog just north of the Namekagon River, and Hoary Elfins on an unmarked firebreak just north of Clemens Creek on the Barrens. See last photo--the tall trees and low shrubs seem to attract mating elfins. Let's call it an Elfin Lek. All photos except the mating Henry's Elfins, group shot, and Lek were taken by Brian Shapiro. Thanks Brian!

Prescribed burns in the area kept me on the northern-most stretch of FR-236/Ino Rd.

Compton Tortoiseshell was my lifer look at one, though it was a quick thrill, as it zipped right at my head, flashed gold/black and it's pattern, but kept on going straight away.

Very good numbers. Duskywing counts are conservative to the masses of them seen. Any scat or damp areas seemed to swirl with them.

Location: Bog off Namekagon Trail, & Barrens

First stop was at a bog off Namekagon Trail, about 1/2 mile north of the Namekagon River. On May 16, our crew found Brown Elfins on the bog. On the 25th, a tromp through the bog found not a single Brown Elfin; they were, however, found sipping nutrients on the road gravel. Dozens of Duskywings that refused to sit still for a photo on the 16th were also much easier to photograph as they sipped on the damp gravel. One Dreamy Duskywing obliged with a shot of the "hair pencil" on its hind tibia. This is missing in the Sleepy Duskywing. Saw no Jutta Arctics and no bog fritillaries out in the bog.
Also saw no Henry's or Hoary Elfins at the "Elfin Lek" just north of Clemens Creek on the Barrens (see 16th sighting), nor were any Silvery Blues or Olympia Marbles seen at either site.
