Description: Golofa clavigera clavigera (Linnaeus) is a type species of genus Golofa, occurring in wide ranges including French Guiana, Venezuela, Brazil, Colombia, Ecuador, Peru, and Bolivia. G. clavigera clavigera is very common among the Golofa species. Its biology has not yet been studied. Identification information can be found in Cespesdes and Ratcliffe (2010), Endrödi (1985), and Hwang (2011).

Euetheola rugiceps.jpg

Comment: E. rugiceps (LeConte) is known to occur southeastern US and keep spreading upward to midwest states. I personally collected couple of specimens in southern Nebraska, 2014. Very common in down south. They are mostly active in between May-June to August. I have experience of collecting more than a hundred specimen in a single night with a small battery-operated blacklight within an hour. This species do not show a sexual dimorphism, therefore, genitalia must be extracted to determine the sex. In my personal collections from Shreveport, LA and Alexandria, LA, there were whole lot more females than males collected.

Comment: An only species under Lucanus, occurring in South Korea is quite common in Gangwon-do, South Korea. Adults fly to the light at night. Males are in range of 30-70mm size in general.  Pictured specimens are my personal collection from Gangwon-do, South Korea, June 2013.

Description: Largest lucanid species occurring in North America with three sister species: L. capreolus (Linnaeus), L. mazama (LeConte), and L. placidus Say. Comparably, easily reared. sizes around 30-60mm. Reddish brown to dark brown colored. As many knwon European and Asian large Lucanus spp., it has ‘a bump’ on head. Adults attracted to the lights in summer. Personally collected one male specimen in Louisiana on July 2016. (below)

Description: one of four species of Chrysina occurs in the U.S. This species is known to occur in the US (Arizona to western Texas) and the Mexico (Chihuahua and Sonora) and are very common species. Alive specimens can be sexed based on its coloration, male being darker green whereas female being brighter green (slight difference presented). Adults feed on foliage of Juniperus sp. Larvae can feed on dead, rotten Quercus sp., and are easily reared to adult stage. Known to fly to the lights in Arizona.

(Pictured specimen is reared male. Image of females will be updated in the near future.)

Description: One of two Dynastes species occurring in North America, the other one is Dynastes grantii Horn, 1870. Two species do not overlap the distribution. D. tityus occurs in Texas-Florida-New York, while D. grantii occurs in Arizona-Utah and northern Mexico. Five female specimens collected with light trap of metal halide + black light and mercury vapor + blacklight combinations from July 1st to July 6th, 2016 in central Louisiana.

Following image is one of those five females in collection site:
