Overview
Linda's roadside skipper (Amblyscirtes Linda) is a small dark brown species of grass skipper known for its quick darting flight patterns. It is endemic to the Ozark and Quachita mountain ranges and uses Indian wood oat (Chasmanthium latifolia) as a host plant for its egg and larval life stages.
Scientific Name
Identification Numbers
Characteristics
Behavior
Linda’s roadside skipper is a non-migratory butterfly. Grass skippers have rounded and short wings that are less efficient for long distances and better suited for short, quick, darting flights.
Life Cycle
The eggs of Linda’s roadside skipper are laid singly on the leaf underside of the host plant, Indian woodoat (Chasmanthium latifolium). The egg and pupal stages are brief and most of the year is spent as larvae. There are five larval instars. Overwinter hibernation likely takes place as a late instar larva, possibly pupa until the following spring or summer in which they emerge as a butterfly.
In 1987, J.R. Heitzman and J.E. Heitzman state there are three broods from mid-April to early September, in contrary to Scott's earlier observations in 1986, who states there are only two in late April-early May and late June-early July.
Physical Characteristics
Linda’s roadside skipper is a non-migratory butterfly. Grass skippers have rounded and short wings that are less efficient for long distances and better suited for short, quick, darting flight patterns.
The adult butterfly is dark brown with hints of orange scaling on the dorsal side. The dorsal forewing has one to few apical spots that are generally small and yellow-white. On the ventral side, the forewing apex is generally darker than the rest of the wing with an apical spot. The dark brown hindwing underside contains nonuniform peppered grey scaling with a weak curved discal spot band. The fringes of the wings are checkered.
The last stage larva has a white head with a brown vertical stripe and blue-green body, as documented by J.R. Heitzman and J.E. Heitzman in 1969. It has two short side stripes on the head that extend to the top of forehead, as documented by T.J. Allen and others in 2005.
Linda's roadside skipper is a small species of grass skipper with pointed forewings. While resting, the wings are partially open allowing for the forewings and hindwings to be held at different angles known commonly as the jet-plane position. They have a bent oval antenna club, with an apiculus on the tip.
Measurements:
Wingspan: 25 mm to 28 mm
Habitat
Linda’s roadside skipper lives in relatively undisturbed mesic hardwood forests with an abundance of the host plant, Indian wood oat (Chasmanthium latifolia), along or near small streams in and surrounding the Ozark and Ouachita highlands.
Land covered by evergreen trees in cool, northern latitudes. Also called taiga.
Food
This species depends on the host plant, Indian wood oat (Chasmanthium latifolia), along or near small streams in and surrounding the Ozark and Ouachita highlands.
Similar Species
Linda’s roadside skipper adult butterfly stage can be indistinguishable without further analysis of the genitalia from its sister species: Bell’s roadside skipper (Amblyscirtes belli), pepper and salt skipper (Amblyscirtes hegon) and common roadside skipper (Amblyscirtes vialis). The caterpillar, or larval stage, is nearly identical to the bronze roadside skipper (Amblyscirtes aenus) and Nysa roadside skipper (Amblyscirtes nysa).
Geography
Linda’s roadside skipper is an Ozark and Ouachita mountain range endemic species that occupies a small area of the lower midwest, including southern Missouri, northern Arkansas and the immediately adjacent parts of Kansas, Illinois and Oklahoma. The species distribution may possibly include Kentucky, Tennessee and Nebraska. Missouri is believed to house the largest populations in the species distribution, but is still considered locally rare since the 1980s.
