Xestoleptura behrensii (Lepturinae)
Xestoleptura behrensii (LeConte, 1873:227)
Leptura Behrensii - LeConte, 1873: 227
Leptura behrensii - Leng, 1890: 198.
Xestoleptura behrensii - Casey, 1913: 261.
Anoplodera behrensii - Swain and Hopping, 1928: 54.
Somewhat rare. Ranges from British Columbia to California. This species can be separated from X. crassicornis and X. crassipes by its antennae, which are narrow and do not have the segments expanded apically. The males may look similar to X. tibialis but are narrower posteriorly and have the basal punctures of the elytra somewhat sparse. The basal elytral punctures in tibialis are separate but densely clustered.
According to Linsley and Chemsak (1976, p. 155), the flight period is from July to September and the host plants are Pseudotsuga, and Picea. These authors provide an illustration of the species (Fig. 41). See also Swain and Hopping (1928, p. 54, plate 7, fig. 76).
Observations on the biology, internal anatomy, or larvae of this species appear to be absent in the literature.
Notes
- There is a single specimen in the Oregon State Arthropod Collection.
- Holotype image available from Harvard University MCZ. According to LeConte's original description, the specimen was collected by James Behrens in Mendecino, California and send to Dr. G. H. Horn.
