Twelve participants enjoyed a beautiful morning, mainly in the downstream section of the wash where there was more water and more vegetation. Because of the lack of water in the upstream side canyon (thanks to pre-trip scouting by Marceline VandeWater) we did not explore that area that has been so productive in previous years. In late morning we added more species among the flowers in the upstream section of the wash. Thanks to Laura Miller, who went early in the morning to pour water in a small depression in the road, we added three species of puddling Blues.
After lunch at the picnic tables at nearby Sears Kay Ruins, in a hike up to the top of the ruins, we added hilltop species Great Purple Hairstreak and Gray Hairstreak, as well as California Patch (among all the Tarantula Hawks that were also hilltopping). Lower down, near the picnic tables, we added “Martin’s” Square-spotted Blue (pictured) in the large patch of Buckwheat.
Thirty species were recorded: Pipevine Swallowtail, Two-tailed Swallowtail, Checkered White, Sleepy Orange, Orange Sulphur, Southern Dogface, Dainty Sulphur, Great Purple Hairstreak, Gray Hairstreak, Marine Blue, Reakirt’s Blue, Spring Azure, Martin’s Blue, Acmon Blue, American Snout, Variegated Fritillary, Tiny Checkerspot, Elada Checkerspot, Satyr Comma, California Patch, Painted Lady, Empress Leilia, Mourning Cloak, Red-spotted Purple, Queen, Common Buckeye, Northern White Skipper, Common Streaky-Skipper, Golden-headed Scallopwing, and White Checkered Skipper.
A bonus was the male and female Springwater Dancer damselflies in the downstream section of Rackensack Wash.
The reason Rackensack Wash is one of the best places to see butterflies in central Arizona is because of the many and diverse species of flowering plants. Thanks to Marianne Jensen, we added four species of plants to our Rackensack Plant List: two lavender colored ones: Hillside Vervain (Verbena neomexicana), False Pennyroyal (Nedeoma nana), a plant with a tiny white flower: Yellow-throated Gilia, and a large Morning Glory: Paiute False Bindweed.
CAzBa has been leading mid-April trips to Rackensack for the past ten years and each year has been different from the others, largely depending upon winter and spring rains. The biggest surprise this year was the lack of any Variable Checkerspots – the most abundant butterfly on all previous trips.

"The USDA is now reconsidering its regulations regarding the interstate shipment of live butterflies. My understanding is that the USDA is likely to propose regulations significantly weakening the already unacceptably lax regulation of these shipments. Currently, the interstate shipment of live butterflies requires a permit from the USDA. The USDA will consider issuing permits for shipping nine butterfly species -- Giant Swallowtail, Zebra Heliconian, Gulf Fritillary, Mourning Cloak, American Lady, Painted Lady, Red Admiral and Monarch. The regulations being considered would allow interstate shipments of American Ladies, Painted Ladies and Red Admirals without any permit.

What Can You Do? Because the USDA listens to public opinion, it is important that you contact the USDA and express your views regarding this threat to wild butterfly populations. Write to: Wayne F. Wehling, USDA-Aphis, PPQ PRA, Unit 133, 4700 River Rd., Riverdale, MD 20737; or send an email message to him at "Wayne.F.Wehling at usda.gov"
