As June moved into July my tomatoes (Solanum lycopersicum) began to produce, and I was able to take over 50 pounds (22.7 kg) to two local food banks. I also canned 7 quarts (6.6 L) of the Romas into pasta sauce and turned 2 pounds (0.9 kg) of the sweet 100’s cherry tomatoes into a jar of sun-dried tomatoes. I had never made sun-dried tomatoes before and was surprised how easy they were to make. I cut off the ends and halved each fruit, then coated them with olive oil and Italian seasoning. I placed the halves skin-side down in our air fryer for 40 minutes at 250F (121C). The recipe suggested I add another 40 minutes at 180F (82C) to get the chewiness found in store brands. The lowest setting on my air fryer is 250/121, so I hedged and put them back for another 30 minutes. I put them in a clean (airtight) jelly jar and into the refrigerator. This should last several months. This last week the heat of summer finally found us and while my tomatoes have slowed down, my jalapenos have begun to take off. When I went out yesterday morning to water and check for ripe fruit, I noticed a new butterfly resting on the tomato leaves. This was a pearl crescent butterfly.
When I went online, I found the pearl crescent (Phyciodes tharos) is a species North American butterfly. It is found in all parts of the US except the west coast, and throughout Mexico and parts of southern Canada. The species reside in open areas such as pastures, road edges, vacant lots, fields, and open pine woods. Color patterns can be quite variable. Males usually have black antenna knobs. The upper side is orange with black borders, while the rear (postmedian) and submarginal areas are crossed by fine black marks. The underside of the hindwing has a dark marginal patch containing a light-colored crescent. The wingspan is from 0.8 to 1.3 inches (21 to 34 mm). Adults find nectar from a wide variety of flowers including dogbane, swamp milkweed, shepherd’s needle, asters, and winter cress. Males patrol open areas for females, and the eggs are laid in small batches on the underside of host plant leaves of aster species (family Asteraceae). Caterpillars eat the leaves and are gregarious when young. Hibernation is by third-stage caterpillars. The species has several broods from April to November in the north, and throughout the year in the deep south and Mexico.
Hybridization between the pearl crescent and other species of the genus Phyciodes have been studied in the past. These studies were done to see whether variation through hybridization could arise and create a new species of Lepidoptera (butterflies and moths) as a result. The pearl crescent has a large distribution (Mexico to Canada), and around the US/Canada boarder three other species of Phyciodes (P. batesii, P. cocyta, and P. pulchella) are present. While all these Lepidoptera share the same genus their genomes are distinct, causing the variation in phenotype. In Wingert et al.’s study on Phyciodes differences, they found that the genome sequence was different because of the low levels of gene flow and hybridization. Even though these species are capable of hybridization, it shows how these butterflies have been able to maintain their separate genomes and not overly hybridize. In other words, these different species are similar but tend to keep to their own kind when mating.
THOUGHTS: While the pearl crescent does not appear to cross breed with “cousins”, several mammal species do, both naturally and in captivity. There are zonkeys – zebras (subgenus Hippotigris) + donkeys (Equus asinus), camas – camel (genus Camelus) + llama (Lama glama), pizzlies – polar bears (Ursus maritimus) + grizzlies (Ursus arctos horribilis) and others. About half of all plant species on Earth arose through hybridization. Even humans have hybridization early in our history, and many people carry a little Neanderthal DNA. Humanity is different than most other animals as we choose what to differentiate us from each other, even though we are all the same. Act for all. Change will come and it starts with you.
