The broad-tipped conehead katydid, Neoconocephalus triops (Linnaeus, 1758), is a coneheaded katydid in the subfamily Conocephalinae.

Within this subfamily, four genera consisting of 22 species total, exist in America. Like all other coneheads, they possess a cone called a fastigium, a projection sometimes sharply pointed, depending on the species from the head that stretches beyond the basal antennal segments.

However, unlike other species in Conocephalinae, the broad-tipped coneheads bear fastigia that are wider than they are long.

Neoconocephalus triops has the most extensive range of all the species within the genus Neoconocephalus. It is found in the Caribbean and North America.This species occurs throughout the southern United States, from Florida up to New Jersey, and extends westward to southern California.

Adult broad-tipped coneheads display either brown or green coloration, depending on the sex and season.

Neoconocephalus, like most adult male katydids, produce a calling song by rubbing their wings together. In order to call mates in late spring, males perch from treetops at night; in early spring and summer, males call from understory and/or weedy areas.

Adult females tend to be larger than adult males, measuring 51 to 67 mm and 43 to 60 mm, respectively. In adult females, the ovipositor is about as long as the hind femur. Their bodies are covered by long, narrow, leathery forewings.

About 95% of males in the overwintering population are brown, while about 30% of overwintering females are brown. Only about 20% of the summer males and females display brown coloration and the remaining adults are green.

Both adult males and females are strong fliers and tend to be attracted to lights. When disturbed, adult coneheads will fly off or dive down into the ground, burying their head to make their body appear as grass.

The eggs are light green in color, and are long and oval-shaped with pointed ends. Coneheaded katydids oviposit in grasses in between stems and sheaths of roots or leaves.

Broad-tipped conehead katydid nymphs are light green, resembling the adults with long, slender bodies, but lack wings and sexual characteristics.The typically green broad-tipped conehead juveniles and feeding adults frequent grasses such as bahiagrass (Paspalum notatum) and Vaseygrass (Paspalum urvillei) to eat grass seed.
