Photo just after he caught a cricket which took hours
for him to consume.  He caught it in the early afternoon
and after I shot three photos using the  flash,
he took it into his cave to enjoy it in peace. 
According to his caretaker, John Richards,
he eats about one cricket a week.


In captivity these Tarantulas will feed on crickets
The crickets like spinach and lettuce

Photos of male Utah Tarantula - Aphonopelma iodius
Tarantulas are nocturnal, sit and wait  predators and stay close to their burrows.  Some female tarantula in captivity have lived 30 years.  Females in captivity are reported to mature at a minimum of seven years in this species - iodius (Chamberlin & Ivie 1939b) and continue to molt throughout their lives.  Females continue to use burrows after maturity but males leave them to find females during the breeding season.

Pronunciation of Theraphosidae  is  Ther - ah - FO - seh - dee or di
