Reduviid bug? - Reduvius

Reduviid bug? - Reduvius
Vail, Pima County, Arizona, USA
April 1, 2007
Size: ~1 cm
Found on stairway at dusk (near rodent nest). Hope to raise this bug to adulthood, but haven't been able to get it to accept anything as food yet. Would like to identify the bug as well as find out what it eats.

Seems to be Reduvius sonoraensis
I found an adult and it has a similar pattern

Moved
Moved from Reduvius vanduzeei.

Moved
Moved from Assassin Bugs.

Assassin bug nymph.
Nice image of an assassin bug nymph, possibly a species of Rhasahus (the "corsairs"). I think they are pretty indiscriminate as to prey, and active mostly at night.

Maybe it´s not hungry?
As a Reduviid (it is!), it shall feed on insects otherwise.

 
It happens sometimes
I've reared Reduviids before (Especially Reduv*ius perso*natus, the Masked Hunter), and sometimes they would refuse to eat for the first few days following capture. I guess, keep offering it flies or other small insects, and it may soon be motivated to eat.
In my experience with rearing R. perso*natus, they rarely refuse a meal once you get them started!

 
Prey selection
I've raised other Reduviids, and tried a range of different food items on this one without success. I've tried offering small crickets, mealworms (and mealworm pupae), termites, fruit fly maggots and a moth. All of these have worked well on other types of insectivorous Reduviids, but have been completely rejected by this bug. I've had it for about three weeks now, so I'm sure it's hungry. While some Reduviids seem to feed on a wide variety of insects, others seem to prefer a much narrower range.

 
Reduvius
Just remembered there is another species of Reduvius in Arizona, much smaller than the Masked Hunter....
