Genus Agra
Synonyms and other taxonomic changes
The classification of the genus Agra is unstable, as it has been treated as a separate tribe or even as a separate subfamily. (1)
Explanation of Names
Agra Fabricius, 1801
2 spp. of Agra reach southmost Texas (2)
Agra is easy to recognize and is arguably the most distinctive carabid genus found in Texas. (1)
The known range in Texas is Cameron, Hidalgo, and Starr counties. (2)
Number of compiled Texas collecting events by month:
April (2), May (1), June (6), July (5), August (2), September (2), October (9). (1)
Arndt et al. (2001) studied the adult foraging behavior of several species in a Venezuelan forest canopy and in the laboratory. All specimens observed foraging in the canopy took liquid or masticated flower parts (nectar, pollen, and sometimes diverse components of the whole flower), or from extra-floral nectaries, or liquid from new leaf shoots. (Riley & King, 2009)
Based on study of larval morphology, Arndt et al. (2001) hypothesized that Agra larvae are predators living under bark. (1)
Life Cycle
Little is know about the way of life of the species of Agra, except that adults are arboreal, many living in the high canopy of tropical evergreen forests; some individuals are attracted to light sources. (Ball & Bousquet 2001)
