Tersa Sphinx (Xylophanes tersa)

Adult Tersa Sphinx moths have a pointed abdomen (though this one is a little bent) and contrasting black markings on hindwings.


Tersa Sphinx (Xylophanes tersa)

One of my favorite moths because they look so streamlined and sleek.


Range:  Massachusetts south to south Florida; west to Nebraska, New Mexico, and southern Arizona; south through Mexico, the West Indies, and Central America to Argentina. 

Food:  Adults take nectar from deep-throated  flowers.  They begin feeding around sunset.  I often see them feeding in our Datura right after the blooms have opened in the evening.

Caterpillar host plants include smooth buttonplant (Spermacoce glabra), starclusters (Pentas species), Borreria, Catalpa, and Manettia species.



Tersa Sphinx caterpillars occur in both green and brown forms.  This is a fairly early instar and only about 3/4" long.

.Tersa Sphinx caterpillars have one large eyespot  and six smaller eyespots in a line down their sides.  In earlier instars, smaller eyespots are barely visible and striping more pronounced.

Spangled Skimmers are common in eastern North America as far west as Kansas and Texas.  Males are blue.  Females are brown with yellow stripes.  They prefer well-vegetated ponds and lakes and slow-moving sections of streams.  (BugGuide)

Okra (Abelmoschus esculentus)



Okra

Growing a veggie with it's origins in climates hotter than ours means it does just fine during our summer.  The exact origin of okra is in dispute, but it arrived in the Americas from West Africa.  (Wikipedia)

Female Eastern Pondhawk

Eastern Pondhawk (Erythemis simplicicollis)

Range:  Quebec and Maine to Florida, west to Mexico, north to Washington.
Food:  Smaller flying insects.
Habitat:  Primarily ponds. Adults often perch on the ground.




Eastern Pondhawk - Male

.
Female and young male Eastern Pondhawks are green with square, black spots on their abdomens.  As they age, males turn blue.  This male Pondhawk photographed by Jo is still showing just a little bit of green on its thorax.  BugGuide has and excellent series of photos showing both male and female Pondhawks are various stages of development.

Although we live up on a rocky ridge, there are evidently enough stock ponds around to provide suitable dragonfly habitat.
