Giant Mesquite Bug

Thasus Neocalifornicus


Nymph Giant Mesquite Bug in the genus Thasus.


This was spotted in the Rancho los Olvera part of the municipality of Corregidora which is characterised by semi-arid climate vegetation where various species of cacti can be seen such as the organ pipe and nopals. Trees adapted to dry climates include mesquite, willows and cypress, near streams and rivers. Thorn scrub and subtropical matorral are also common.


There are some academic essay and articles published in Spanish in Mexico that refer to this bug as part of traditional food in some regions. In Hidalgo are known as "Xamui" and in Queretaro as "Tantarrias". In academic essay from Universidad Autónoma del Estado de Hidalgo, this bug is called as scientific name Thasus Gigas.
