Peck's Skipper Polites peckius

Peck's Skipper is a somewhat common sight in Maryland, found mid-July every year. This individual was taken on July 18, 2008 at Brookside Gardens.



Shots below showing the class Peck's Skipper pattern. The lighter marks below can vary among individuals.





Above, the stigma is visible.



Several anatomical features can be seen here. The proboscis is double-barreled. The tip of the antenna is two-toned (orange above, darker brown below) and shows the hooked apiculus characteristic of (almost) all skippers. Additionally, the tibia on the legs have two spikes each.

The Fiery Skipper Hylephila phyleus

The Fiery Skipper is a grass skipper common in the South, less so in Maryland. This particular individual was taken on July 18 at Brookside Gardens in Wheaton, MD.


The underside is distinctive, resembling few other grass skippers (compare to The Whirlabout)





Above, the orange color intrudes into the marginal brown bands on both the fore- and hindwing, resembling tongues of flame (hence the name "Fiery Skipper"). The black stigma that runs from the base of the wing to the cell indicates that this is a male. It releases pheromones that help the female find a suitable mate.


The view of the genitalia confirms that this is a male -- note the claspers.



Don't the faces look friendly? The white circle around the eyes is noticeable here.



One more artistic shot.

Allegany Co. Count 7/11/08

This was my first foray into Allegany County, home to the uncommon and beautiful Northern Metalmark. As with Carroll County, the numbers were low, but a couple of unusual butterflies were sighted.

Highlights

The show-stealer was the Northern Metalmark. These gorgeous creatures are two-toned. The dorsal side is dark brown with two thin metallic bands on margin and post-median. The ventral side is maple-colored with the same bands. The result is a butterfly that flashes two colors in flight. Flight, now, is rare with these. The Northern Metalmark is unquestionably the most sedentary butterfly I've seen. In fact, spotting them was a matter of looking for them on their choice nectar plants: Butterfly weed, a smallish species of sunflower, and goldenrod.

Northern Metalmark Calephelis borealis






The eyes are a striking steel-gray. This flower resembles New Jersey Tea, but I don't know what it is.



Below, the silvery bands are visible against the mapley-orange color.



Another treat was the Aphrodite Fritillary. This butterfly differs from the Great Spangled only in the hindwing below: the Great-Spangled has a cream band in the post-margin that the Aphrodite lacks. The result is that the Aphrodite appears more starkly silvered than the Great Spangled.
The Great Spangled shown in the two pics below was confused. He kept following the Aphrodite in an apparent attempt at mating. He was unsuccesful, but he did manage to provide an excellent comparison specimen!

Aphrodite Speyeria aphrodite
The Great Spangled is in the background. In the hindwing submargin, he has the cream-colored band, partially chewed on this side, that is lacking in the Aphrodite.





The lack of the cream hindwing band combined with the chocolate color of this individual (more typical of the female) brings out the silvery spots quite nicely.




To our great delight, a Zebra Swallowtail popped out of nowhere and sampled the Dogbane long enough for a photo shoot.

A Northern Pearly Eye almost escaped detection against the bark of the tree here.

Roadside and Delaware Skippers joined the usual suspects (Silver-Spot, Dun, etc.) this year.

Carroll County Count 07/05/2008

The Carrol County, MD Butterfly Count 2008 had low numbers but interesting diversity. The weather was rainy in the morning but mostly sunny by late day. Accordingly, we found more species as the day wore on. The greatest disappointment was that the traditional spot for Baltimore Checkerspots yielded none this year (under complete overcast and light drizzly conditions).

The real treat was discovering that one of our Banded Hairstreaks was more likely a Hickory Hairstreak.

Satyrium caryaevorum. Note the blue lunule on the hindwing that protrudes out past the surrounding orange lunules. Note also that the pairs of lines in the disc are aligned with each other (contrast the shots of the Banded Hairstreak above).

On Little Pipe Creek we found a single Snout Butterfly, so named because of the unusual labia. Snouts are very cute.

In the same location, Bob noticed that one of my "Orange Sulfurs" was actually a Sleepy Orange.

Unfortunately, he was unwilling to cooperate for photographs. We got just enough for an ID.

This appears to be the year of the Pipevine Swallowtail. We saw one on the count (unusual), several in Allegany County, and I even found one in my yard. Too bad my pipevine isn't mature enough for caterpillars.
