Batyle ignicollis oblonga

Casey, 1912

Batyle ignicollis oblonga is a of longhorned beetle in the Cerambycidae, described by Casey in 1912. It belongs to the Cerambycinae and tribe Trachyderini. Field observations indicate are associated with flowering plants in sand dune , where they have been observed resting on inflorescences.

Habitat

Sand dune with associated flora. Observed in riparian zones adjacent to dunes where Styllingia sylvatica ('s delight) and other flowering plants occur. Also documented in gypsum/red clay shortgrass prairie environments.

Distribution

North America. Documented from northwestern Oklahoma (Beaver Dunes area), with distribution extending into adjacent regions. GBIF records indicate presence in Canada (CA) and Mexico (MX), though specific localities within these countries are not detailed in available sources.

Seasonality

active in spring, with observations in May. One report notes hundreds of individuals observed in early June, suggesting peak activity during late spring to early summer.

Host Associations

Styllingia sylvatica - resting site observed bedded down on inflorescences, apparently for overnight resting. Multiple individuals found on same plant.
Opuntia macrorhiza association in prickly pear cactus environments, though not confirmed as direct
Neltuma glandulosaSynonym Prosopis glandulosa (honey mesquite); context in mesquite chaparral

Behavior

exhibit a characteristic resting posture on flower inflorescences, particularly in evening hours. Observed to be relatively sedentary when at rest, allowing close approach. Slow, deliberate movements noted. of hundreds of individuals observed on flowering plants in some locations, though typically encountered in smaller numbers.

More Details

Taxonomic note

This was described by Thomas L. Casey in 1912. The Batyle belongs to the diverse longhorned beetle tribe Trachyderini, which contains many flower-visiting in North America.

Field observation context

During a 2013 collecting trip, an observer noted 'huge numbers' of this at Beaver Dunes State Park, Oklahoma—far exceeding typical encounter rates. All individuals were perched on yellow-spiked inflorescences of an unidentified plant (later determined to be Styllingia sylvatica) in a characteristic pose suggesting they had bedded down for the night. This represents an unusual event.

Predation note

have been documented as prey for reduviid assassin bugs (Apiomerus spissipes), which were observed feeding on both male and female B. ignicollis at flowers.
