Colias cesonia - STOLL 1790 - Southern Dogface



Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Suborder: Ditrysia
Superfamily: Papilionoidea
Family: Pieridae (Duponchel, 1835)
Subfamily: Coliadinae
Genus: Colias
Species: C. cesonia

The Southern Dogface, Colias cesonia, is a American butterfly in the family Pieridae, subfamily Coliadinae (sometimes it is placed in the related genus Zerene instead of Colias).

The upper side of the pointed fore wings have a dogface pattern. The wings are mainly yellow with black borders. The under side of the wings is mostly yellow with a black eyespot on the fore wing and two white spots on the hind wing.

This butterfly can be found in short-grass prairie hills, open woodlands, and near road edges. Both male and female Southern Dogfaces may be seen feeding at flowers such as Alfalfa, Coreopsis sp., Houstonia sp., and Verbena sp.. Males are also fond of puddling. Its host plants include Lead Plant Amorpha canescens, False Indigo Amorpha fruticosa, Soy Bean Glycine max, Alfalfa Medicago sativa, Black Dalea Dalea frutescens, Purple Prairie Clover Dalea purpurea, and clover Trifolium sp.. Males patrol areas for females. The male is the active flight partner. The green-white eggs are laid on the underside of the host plant leaves. The larva is green with a white stripe running down each side of its body. The green chrysalis hangs up right with a silken girdle around itself.

Smyrna blomfildia FABRICIUS, 1781



Blomfild's Bark Wing
Smyrna blomfildia FABRICIUS, 1781
Family - NYMPHALIDAE
subfamily - NYMPHALINAE
Tribe - NYMPHALINI

Introduction

The tribe Coeini comprises 6 genera - Colobura, Baeotus, Historis, Pycina, Smyrna and Tigridia.

There are 2 species in the genus Smyrna, namely karwinskii which is found in Mexico, and the more widespread blomfildia which is distributed from Mexico to Bolivia.

Habitats

This species is found in primary and secondary forest at altitudes between sea level and 1200m.

Lifecycle

(?)

Adult behaviour

Males of Smyrna blomfildia are often seen in aggregations of a dozen or more, imbibing mineralised moisture from rocky overhangs, stone walls, or tree boughs. They also visit fallen fruit on the forest floor, or in orchards.

When resting or feeding the butterflies usually keep their wings closed, but if disturbed they will flick them half-open momentarily. They are not nervous in disposition however, and in the presence of human intruders they will continue feeding long after most other species have fled.

In common with their relatives in the genera Colobura and Tigridia, they roost overnight on tree trunks, on which they are superbly camouflaged.

Eueides isabella (Stoll, 1781) -Isabella's Heliconian or Isabella's Tiger



Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Nymphalidae - Brushfooted Butterflies
Subfamily: Heliconiinae - Heliconians and fritillaries
Genus: Eueides
Specific name: isabella
Scientific name: Eueides isabella (Stoll, 1781)

NOTE: I'm not sure, but I think this may be sub-species: "Eueides isabella dynastes - C. &. R. Felder, 1861" - Found only in Venezuela and Colombia.

Description: Eggs are cream coloured and approximately 1 x 0.9 mm (h x w). Females usually place 1 to 3 eggs under older and younger leaves of the host plant. Mature larvae have a black body with orange and yellow stripes and white bands, with black and white scoli and head, orange anal cap; length is around 1.7 cm. Caterpillars are gregarious in small numbers (Brown, 1981). Pupae are greenish white with black markings on the wingpads and short spines on dorsum that are tipped black (DeVries, 1997).

Habits: E. isabella occurs from sea level to 1,500 m in secondary forests. Females mate multiply, often on hilltops. Adults roost solitarily at night under leaves (Brown, 1981).

Hostplant: E. isabella larvae feed primarily on plants from the subgenera Distephana and Granadilla (Passifloraceae)(Brown, 1981). In Costa Rica larvae feed on Passiflora platyloba, and P. ambigua (Passifloraceae) (DeVries, 1997).

Distribution: Eueides isabella is widely distributed from Central America to Brazil and also on the Greater Antilles. The map below shows an approximate representation of the geographic distribution of this species.
