DISTRIBUTION:

Lintneria merops merops (wingspan: 103-122 mm, females larger than males), flies in
Honduras (specimen type locality) and from western S. America, including Venezuela, to
Mexico;
Belize: Cayo;
Nicaragua: Jinotega, Matagalpa, Masaya, Granada, Isla de Ometepe, Rio San Juan;
Costa Rica: Guanacaste, San Jose, Alajuela, Lemon, Puntarenas, Heredia, Carthage.

In his The Hawk Moths of North America, 2007, James P. Tuttle has assigned all the Sphinx genus species from Mexico south throughout South American to Lintneria, Butler, 1876, based on consistent differences in wing characters and significant larval differences.

FLIGHT TIMES:

Lintneria merops merops adults fly in Costa Rica from April until January.

ECLOSION:

Pupae probably wiggle to surface from subterranean chambers just prior to eclosion.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen. Adults pollinate orchids.

EGGS, LARVAE, PUPAE:

Larval hosts are Lantana camara and probably other members of the Verbenaceae family. The third instar has a dermal crest and yellow eye-spots on sides; there are 2 black eye-spots on last two instars.

The pupa has a long flat tongue case. Moths emerge about fifty days after pupation, but some which pupate in July, emerge in November.

Larvae are subject to parasitization by Belvosia sp. 6 of the Tachinidae family.

Please visit my special request for images of Lintneria species larvae at Lintneria larvae, and help if you can.

It is anticipated that the Lintneria larvae will most often be encountered on Lamiaceae: Salvia (Sage), Mentha (Mints), Monarda (Beebalm) and Hyptis (Bushmints); Verbenaceae: Verbena and Lantana camara (shrub verbenas or lantanas).

Although they may be encountered feeding during daylight hours, one is even more likely to discover them feeding in the evening or after dark.

Two of the greatest clues for discovering larvae are stripped foliage and droppings beneath the plant. You might be quite surprised at what will turn up in the evening or after dark in a flashlight assisted search.

It is believed that all "Lintneria larvae will exhibit "a fleshy thoracic dorsal "horn" in the first 4 instars (unique in the Sphingidae of the world to my knowledge) which is replaced by a thoracic dorsal "hump" with a large black patch in the 5th instar." J.A. Tuttle.
