Sunday (ecological) Storytime:
I wanted to share a little moment of discovery with y'all that brings together this beautiful white flower, with the small butterfly you see in the photos, please enjoy.
Skippers - Hesperiidae - are that ever so common group of butterfly, very darty in their movements with the tight upright wings, looking like a small paper football. There's 275 species of them native to North America and today I saw a new one for me. One blurry photo and some internet sleuthing (shout out iNaturalist.org) later it turned out to be a Common Checkered Skipper (Burnsius communis) which has a pretty expansive range - southern California up into central Ontario and everywhere in between it seems. Some further research on ButterfliesandMoths.org revealed that it has several host plants or plants it needs to raise its caterpillars on - across that range. They are all in the Mallow family - Malvaceae.
However, we're here in Pennsylvania and so I wanted to see what it might be feeding on in our eco-region. When we start looking at its host plant species that are found in our part of Pennsylvania that list drops off abruptly. Sure some people plant non-native mallow, some mallow species grow as non-native weeds - some people plant Purple Poppy Mallow (Callirhoe involucrata) and other species ornamentally that are native to the midwest but none of those historically existed in eastern Pennsylvania.
Of the seven FAMILIES of plants that are listed as host plants there is only one that actually overlaps with Berks County - Sida - and specifically the Virginia mallow (Sida hermaphrodita). Which brings us to the first photo in the series...
Virginia mallow is a critically imperiled species in Pennsylvania that has not been documented in Berks county in over 25 years and is currently only known in the Susquehanna region as best as I could discern. This status is primarily due to irresponsible development and habitat loss. It's a massive wetland plant - sometimes getting over ten feet tall with hibiscus like leaves and tiny white flowers blooming in late summer. I had the opportunity to buy this individual from a small specialty nursery some years ago and I have been growing it in a large pot waiting for the right spot - or client's property - to plant it at. It's not an easy plant to find a home for in most garden settings and given its rarity finding local seeds is very difficult.
And so how is this species of butterfly persisting in an area where its singular native host plant has virtually been extirpated? Well likely it is utilizing some of the non native species in the family such as Malva neglecta (buttonweed) which is fairly common in the area or relying on those planting mid-western native species ornamentally. All the while keeping a vigilant eye out for the host plant it would have historically used in our eco-region. As many challenges as we have thrown at out native pollinators they are doing their best to persist.
I can't say for certain that this little skipper grew up eating the leaves of this Virginia mallow but I like to think that she did. And I think to think that that little caterpillar grew up stronger for having had the species she co-evolved over millennia to enjoy.
At Wildcraft Landscapes we're trying to not just heal our ecosystems through how we garden, we want to connect our clients with those ecological processes and stories that connect all beings. The wonders of the natural world are out there to be discovered.
