Habitat and Range

Habitat

"Riparian" Arroyos and river basins Flood plain "forests" of the southwest & usu. associated with ecosystems plentiful in Cottonwoods, Willows, and Sycamore (+ adj./associated Hardwood forests and grasslands)

Geographic Range

"Desert southwest" Replaces the T. dealbatus-pronotalis group in the arid Southwest Well known from Arizona and northern Mexico. Reported from the following: Arizona, w. New Mexico, s. Colorado, and w. Texas* (reports from w. TX are not confirmed & remain suspect/unlikely?) *NOTE: Some cultriformis reports may be based on the similar looking T. dealbatus, which may be duller in coloration across parts of its southwestern range - incl. TX, NM, and CO).

Seasonal Activity

June-November

Diet and Behavior

Diet: It is thought this species (much like the related taxa - pronotalis & dealbatus) seems to prefer sycamores (Plantanaceae), cottonwoods & willows (Salicaceae) Also reported from, but less commonly associated with, misc. other flood plain hardwoods.

Life History

eggs usually laid in dead twigs, wood or bark (occasionally eggs may be laid in living stems and twigs) eggs hatch and nymphs burrow into the soil nymphs feed on the sap in roots for several years (prefer Pines) Final instar nymphs emerge and develop into winged adults (emergence for this species usu. occurs at night)

Additional species information

Species notes from the sources

Etymology: From Latin culter- "knife, plowshare" + forma- "form, shape, appearance" According to Davis: "But the greatest differences are in the lower pieces [of the male genitalia] into which the uncus locks, which are 5 millimeters long in cultriformis , and when seen in profile are shaped like the blade of a pruning knife, hence the name."

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group

Order-level background for Hemiptera, the group containing Megatibicen cultriformis. Species-specific details appear above.

Group overview

Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.

Ecological role of the group

Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.

Economic and practical significance of the group

The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.

Recorded sources for this group: USDA, EPA, University research. Imported estimates may describe particular regions or reporting periods.
