Genus Kymachrysa
Synonyms and other taxonomic changes
Species were originally described under Chrysopa. Transferred to Ceraeochrysa by Adams (1982), with both species lumped by Garland (1985). Transferred to Chrysopodes (Neosuarius) by Tauver (2003). Placed as incertae sedis by Freitas et al. (2009), with both species re-split by Tauber and Flint (2010). Described as a new genus, Kymachrysa, by Tauber and Garland (2014).(1)
Explanation of Names
Kymachrysa Tauber & Garland, 2014
from the Greek κύμα (kýma), ('wave' - referring to the sinuate longitudinal veins) + -chrysa (referring to green lacewings)
from the genus Chrysopa, derived from the Latin chrys-, after the ancient Greek χρυσός‎, ('gold') + ōps ('face'), referring to the family's golden eyes
Numbers
2 species in our area as the only known species:(1)
1. K. intacta (Navás, 1912): widespread (Canada: ON, QC; United States: AZ, CA, CO, MN, MO, NC, NH, NM, NV, NY, OR, TN, TX, UT, WI, WV, WY)
2. K. placita (Banks, 1908): infrequent in the western US (AZ, CO, NM, UT, WY)
Identification
Kymachrysa is one of several genera with a pale streak down the body and is distinguished by its sinuate longitudinal veins, between the inner and outer gradate veins. In most other green lacewing genera, the longitudinal veins are essentially straight.(1)
Range
North America(1)
Habitat
For K. intacta: Eggs are laid on the trunks of deciduous or evergreen trees, and the debris-carrying larvae form their debris packet from the woody material of these trees.
Season
Adults: June - mid-October, most prominent in August(1)
Life Cycle
For K. intacta: Eggs hatch into the first instar larvae around September to October. Development is influenced by the length of daylight. They overwinter as second instar larvae until about March to April. They pupate and then emerge as adults in June, with adult activity peaking in August. Adults lay eggs on the trunks of deciduous or evergreen trees from July into late September to early October, and adults die around mid-October.
