2018 Butterflies: A Top 10 List

2018 has been a very good year for butterflies in Eliza Howell Park. Recently I saw the 30th different species of the year (30 species that I was able to identify; there are some small brown skippers that I do not know well enough).

It was also a good butterfly year in that I was more successful in photographing them, learning to get close enough to capture them with a phone camera. The pictures here were all taken in the park this year.

This list could have been considerably longer, but these ten are the ones that I’d like to call to the reader’s attention at this time.

Though called “common,” I don’t see many Common Buckeyes in Eliza Howell. When I do see one, it is usually late in the season. They are a more southern species, at least for much of the season. In Michigan in football season it may be appropriate to point out that the “Buckeye” name has nothing to do with Ohio. 

Black Swallowtail (first seen May 29; photo September 7)

Male and female Black Swallowtails look a little different; this is a female. Black Swallowtails are common and are often found in gardens. Parsley family plants serve as food plants for the caterpillars.

Viceroy (first seen August 4; photo August 10)

Viceroy butterflies look like Monarch butterflies and benefit from the Monarch’s reputation among birds for being toxic. Ordinarily, Viceroys have a clear black band across the hindwings (a line which Monarchs do not have), but that line is extremely faint in this one.

Monarchs are the most famous butterfly in country, known for their annual migration, their dependence on milkweed plants, and their recent decline in numbers. I don’t know the long-term implications, but there were a great number of Monarchs in southeast Michigan this year – and in Eliza Howell Park.

Tiger Swallowtail (first seen May 31; photo August 2)

Tiger Swallowtails were also common this year, showing up frequently throughout the summer.

Silver-spotted Skipper (first seen June 24; photo July 26)

Roughly one third of all butterfly species in North America are skippers and, as a rule, they are very difficult to identify. The Silver-spotted Skipper is the most easily recognized of the skippers, perhaps reason enough to like it.

Common Checkered-Skipper (first seen June 29; photo July 24)

The Common Checkered-Skipper, considered the most common and widespread skipper in North America, is also relatively easy to recognize. The males sometimes appear a little blue.

Giant Swallowtail (first seen July 17; photo July 17)

The Giant Swallowtail is fairly common in more southerly regions of the country, but not here. I feel fortunate any year that it shows up in Eliza Howell. Compared with many butterflies, it is indeed a giant.

American Lady (first seen May 31; photo July 14)

American Lady and Painted Lady are both found here; this year I saw American Lady a little more frequently. The Ladies, especially Painted Lady, migrate seasonally as Monarchs do.

Hackberry Emperor (first seen June 11; photo June 11)

I don’t know why a small family of butterflies is called “Emperor,” but the “Hackberry” name comes from the fact that the hackberry tree is the larval food plant. They are not common in Eliza Howell.

In the middle of September, butterfly activity is slowing down and the Monarch migration to Mexico is well started. But there are still some butterflies around and it is not too late for a butterfly walk.
