Are these Dubia roaches?

[Murray of the Deep]

I think you may be right.

I live in the philippines and i found them under the soil they dig quite fast and is strong and also do they eat cabbage??

Blaptica dubia are endemic to Central and South America - these are some burrowing species from SE Asia.

These also appear to be at least predominantly nymphs... you'll need to get in touch with someone familiar with your local insect fauna. Keep in mind there are some 500 genera of Blattodea ; )

I should also add they they will probably be OK to feed to your herps so long as you are certain they did not come into contact with any chemical pesticides, herbicides, etc in the garden. Poke around at them and handle them some and see if a defensive odor is emitted - if so these are sometimes quite foul to the senses but overall nontoxic and palatability will vary herp to herp.

here's a picture of the adult which I got earlier because the 1st pic was all eaten by ants so here i captured another batch and found one adult , now what is that roach? is it a giant burrowing cockroach?or are they beetle roaches?

[Murray of the Deep]

is it a palmetto bug?? will they accept carrots and cabbage? or cooked rice?i want to culture them for my frogs!! will they eat?

Give me a little time - I'm going to shoot the photo of the adult off to a friend of mine (Kyle Kandilian). As far as I'm concerned, if he doesn't know what species this is, no one will. He's usually pretty prompt to reply to me, but allow for a couple of days in case he's busy and doesn't have time to tend to his emails.

They will accept all of the above food items that you've mentioned. The term 'palmetto bug' can be applied to roaches but is most often used to describe the pest species (American cockroach, Periplaneta americana).

Cooked rice is fine, along with any other grain product. They should eagerly consume anything that you would otherwise offer to crickets or mealworms as food. Carrots, apples, cabbage, etc are all perfectly fine to feed as a moisture source.

Definitely not a giant burrowing cockroach or a beetle mimic...if it was the prior I'd be paying you to ship it to me LOL ; ) We'll see what Kyle says. Insect taxonomy can be pretty challenging, I work with identifying Tachinidae and various hymenoptera almost daily and to differentiate species it can take a lot of keying out and identification of characters under a dissecting microscope. Thankfully, roaches are a little larger and more dramatic in their individual morphologies, but being a species from the Philippines I cannot guarantee that anyone I know in North America can readily ID it on the spot without references.

The Roach God has spoken:

"These are either Pycnoscelus surinamensis or P. indicus. The latter is the parent species of the former; P. indicus populations consist of males and females but P. surinamensis is all female. The location suggests there's a strong chance they're either." -Kyle Kandilian

thanks a bunch! they are Pycnoscelus surinamensis! and also does it mean that they are different species with all males and female? pretty cool!
