Butterflies Seen

Before getting to the results I just want to say thank you once again for coming out. Each group contributed rather significantly to the overall total number of species, as witnessed by the high number of single sightings. We had record numbers of 2 species: Orange Sulphur (80) and Golden-headed Scallopwing (158). New for the summer count was a Tropical Leafwing.

The day was quite warm, in the high 80's F by the end of the field trip. We first searched for butterflies near the White Rock campground, followed by the area around the gravel parking lot on the south end of the lake, and finished with both sides of the cove at the Lower Thumb Picnic area. A few of us also stopped at the butterfly garden at Tumacácori NHP on the way back home. The group found and identified 34 species. The species marked with * were not seen by the entire group.

29 people participated in this year’s count, split up into 10 groups. The above average rainfall for the previous four months (Dec 2023-March 2024), combined with below average temps for each of those months has resulted in noticeably fewer butterflies at this time of year, even in the lower elevation (midtown Tucson). While a survey later in April may have resulted in more individuals and potentially more species, we would have missed the window for things that normally fly at this time. A major weather system that pushed through the area three days beforehand may have also resulted in the absence of a few species which were seen the week prior. The weather during the survey was nearly perfect (sunny and a high of 83degrees) and if we had 3-4 more similar days prior I suspect numbers would have been better all-around but when looking at the bigger picture it’s all quite interesting!
There was one new species added to the count, Theona Checkerspot, which has never been recorded on the spring or summer counts. This species was presumably only known from Peppersauce Canyon, and may have expanded its range after the Bighorn Fire in 2020. iNaturalist records seem to support this with 1 record from the front range in 2020 followed by numerous records in 2022 & 2023. The host plant for this species, indian paintbrush (Castilleja sp.), is a fire adapted species that readily reseeds after these events. It will be interesting to see whether this species continues to maintain the range extension or contracts over time.
