In order to understand how subpackage works I have created a simple project.

So, if I set module name: 

/* in insects/src/bee.d */
module insect.bee;
...

dmd complains about module bee 

$ dub
src/app.d(1,8): Error: module bee is in file 'insects/bee.d' which cannot be read

If I remove module name 

/* in insects/src/bee.d */

//module insect.bee;
...

and import just file name: 

// in src/app.d 

//import insects.bee;
import bee;

void main() {
  ...

it works.

So, I cannot use module declaration in my subpackage?

Thanks

The directory structure must correspond to the fully qualified module name in order for the compiler to be able to find it. So in this case you'd have to put the bee.d file in a sub folder src/insects/ instead of directly into src/. It unfortunately creates a bit of redundancy, but there is usually no way around it (always compiling with dub build --combined would also make it work, but that's a rather questionable workaround).
