SPHINX or Hawk Mothssee also PL

Family Sphingidae

Identification: Medium-sized to large, heavy-bodied, with wings relatively small. Antennae thickened, somewhat spindle-shaped apically. Sc and Rs in HW parallel to end of discal cell and beyond, connected by an oblique cross vein about opposite middle of discal cell. Frenulum present but sometimes small.

Sphinx moths are strong fliers, with a very rapid wingbeat. They feed on flowers, much like hummingbirds. Most species feed at dusk or at night; a few feed during the day. Some species have large areas of the wings devoid of scales and resemble bumble bees. Larvae of most species have a soft spinelike process near the posterior end of the body and are often called horn-worms; some are pests of tomatoes, tobacco, and other plants. They usually pupate in the ground.

Macro-Moths, Group 2

Cu in FW appears 3-branched. The families in this group may be divided into 4 groups on the basis of venation in anterior part of hind wing.

1. Sc + Ri and Rs diverging at base of wing: Dioptidae, Saturniidae, Citheroniidae, Lacosomidae, Epiplemidae.

2. Sc rather abruptly angled into humeral angle of wing, often connected to humeral angle by a cross vein; beyond this bend Sc and R are either fused or are closely parallel for a short distance along anterior side of discal cell: Geometridae, Manidiidae.

3. Sc and R approximately parallel along basal half of discal cell, then connected by a distinct cross vein, diverging beyond the cross vein: Bombycidae.

4. Sc + Ri and Rs close and parallel along at least basal half of anterior side of discal cell, often farther, then diverging: Thyatiridae, Notodontidae, Zanolidae.
