Wing span: 1 5/8 - 2 3/4 inches (4.2 - 7 cm).

Caterpillar hosts: Plants from the snapdragon family including snapdragon (Antirrhinum), toadflax (Linaria), and Gerardia; the plantain family including plantains (Plantago); and the acanthus family including ruellia (Ruellia nodiflora).

Females lay eggs singly on leaf buds or on upperside of host plant leaves.

Habitat: Open, sunny areas with low vegetation and some bare ground.

This specie of butterfly I have spotted several times in the meadows this year. Of all the times, this is the only picture I was able to get with its wings closed.

Later in the season, the size of these butterflies seemed to become smaller, not only in Crex Meadows but in other locations where I encountered them. I do not know if this was an effect of the dry summer. All locations in 2007 where I observed this butterfly later in the season, were affected by lower rainfalls.

Sighting Chart

sightings chart

In the chart above, if the floor of the chart area has color, it means I was on Crex Meadows that week but saw 0 of this species. Example - May 21 - 25 I was on Crex Meadows in 2010, 2014, 2015 and 2016 but recorded no Common Buckeyes during those visits.

The Common Buckeye is one of the migrants into Crex Meadows. In 2012, after a very mild winter in the USA, the Buckeye survived further north than is typical, resulting in the large numbers for these butterflies. 2014 I had one sighting of one Buckeye and 2015 I saw no Buckeyes.
