Anavitrinella pampinaria - Hodges#6590 (Common Gray).
Size: approx. 25-30 mm. Photo: 09/13/14, 10 pm.

The Common Gray can be found in most parts of North America. The color of its wings varies from medium gray to light yellowish-gray with heavy dark gray or black mottling. The larvae are light brown and mimic twigs. They are known to feed on apple, ash, clover, elm, pear, poplar, and willow.

Besma quercivoraria - Hodges#6885 (Oak Besma).
Photo: 04/29/17, 10 pm.

A flying leaf! This fairly large moth looked rather pretty and was clearly attracted by our porch light. Its larvae are twig mimics and feed on leaves of oak, elm, poplar, willow, white spruce, and paper birch. Adults are sexually dimorphic but I'm not sure whether this is a female or a male (the former are paler and less boldly patterned).

Chlorochlamys chloroleucaria - Hodges#7071
(Blackberry Looper).
Size: approx. 17 mm. Photo: 03/11/17, 10 pm.

The first moth entry of 2017. Lynn Scot on describes this species as follows: "Wings somewhat pale grayish green, sometimes appearing slightly bluish. On the forewing, the cream-colored antemedial and postmedial lines are clearly defined, but somewhat variable as to straightness. On the hindwing, only the postmedial line is present. A pale terminal line is sometimes evident. The fringe is also pale, sometimes a paler shade of the blue-green of the wing. The surface texture of the wing often appears somewhat alligatored."

Costaconvexa centrostrigaria - Hodges#7416
(Bent-line Carpet).
Size: approx. 20 mm. Photo: 05/14/15, 9 pm.

Found in most parts of North America where it is the only species in this genus. The Bent-line Carpet is also an introduced species in the UK, the Canary Islands, the Azores, and Madeira. It is easily confused with Orthonama obstipata but doesn't have an blackish dash at the apex of forewing. The small photo (06/03/15) shows a different specimen.

The Somber Carpet is found in sub-Saharan Africa and in the Americas it ranges from Bolivia and Brazil to Mexico and the United States, where its range extends into eastern Canada. In Hawaii, where D. stellata was introduced in 1993, the larvae are known as Bougainvillea Loopers.

Eupithecia sp..
Photo: 04/22/15, 10 pm.

Eupithecia has over 1400 species worldwide and is by far the largest moth genus. Pugs are typically small with muted colors and species-level identification may require dissection. As a group they are easily identified by their narrow wings held flat at a right angle to the body with the hindwings almost hidden behind the forewings.

Hypagyrtis unipunctata - Hodges#6654
(One-spotted Variant).

Also called called 'White Spot' in the UK, this highly variable moth is not very common in Florida. Its habitat are deciduous and mixed woods. Larvae are twig mimics and have a mottled gray appearance. They overwinter exposed on tree bark and branches. The wingspan of this specimen was about 4 cm.

Macaria bisignata.
Photo: 08/18/14, 9 pm.

This pale brown moth has a wingspan of about one inch. It's larvae feed almost exclusively on pine, so they should be quite happy in our neighborhood. The four dark, brownish spots along the front edge of the forewing (this edge is called costa) are characteristic.

Canadian Melanolophia? I hope this moth has a proper visa! The genus has five species in North America. It has mottled, brownish or grayish wings and often a sea-gull like, dark feature near the center (which seems less obvious in this specimen). The larvae feed on a various trees including pines and oaks. The small photo below shows a female (photo from 05/13/15).

Nemoria sp..

Nemus is the Latin word for pasture or grove and the source of this moth's name. The genus Nemoria has over 30 species of which some show seasonal polyphenism giving rise to populations of brown or green moths.

Nepytia sp..

Nepytia can be found in conifereous and mixed forests throughout North America where the genus has twelve species. Based on location and month, an expert suggested that this might be Nepytia semiclusaria - Hodges#6908 (Southern Nepytia).

The larvae of the Oak Beauty feed on leaves of a variety of deciduous trees including birch, cherry, elm, hawthorn, oak, poplar, and willow. Their body is short and stout for a geometrid caterpillar mottled with browns and grays. Each spot on the head is made of ten to 20 speckles and the body has raised warts on the second and eighth abdominal segments and ventral warts on the third.
