Cryptocephaline on Creosote Bush - Pachybrachis mellitus - male - female

Cryptocephaline on Creosote Bush - Pachybrachis mellitus - Male Female
Goldfield Mountains, Maricopa County, Arizona, USA
October 11, 2008
Size: 4 mm
This is a pretty common species on Creosote Bush (Larrea tridentata). I've found it in spring and fall. Color matched yellowed leaves perfectly.

Moved from Pachybrachis.

This is Pachybrachis mellitus
This is Pachybrachis mellitus. I too have only found it on creosote bush and only when in bloom. It apparently blends in well with the flowers. Ova are easy to collect from cryptocephalines as the females usually just drop them off of the host when they are done forming the egg case. Larvae of most species feed on leaf litter and other detritus and will use the egg case as their first larval case and add on to it throughout the larval period. This species has not been reared through.
