Chrysina adelaida (Hope, 1840)

( Figures 6, 7 , 19 )

This is a common and widespread species, found throughout most of Mexico. We are aware of specimens of C. adelaida from every state of Mexico north of the Isthmus of Tehuantepec except Baja California and Baja California Sur. It has been found in pine-oak forests at elevations between 1300 and 3000 meters above sea level. Numerous specimens have been found in the Sierra Azul in Santa Inés del Monte at 2300 m, and in the vicinity of Santiago Clavellinas (2100–2300 and 2745 m) in pine-oak forests (5 males and 4 females) during August–Sep-tember 2018 and July 2019. There are several common color morphs of C. adelaida from reddish striped ( Fig. 6 ) to mostly green ( Fig. 7 ). Adults of C. adelaida are known to feed on the needles of pine trees ( Pinus species).
