Based on prior knowledge, it is expected that blood insulin levels may differentiate between senior and non-senior individuals. However, the specific ranges of values that differentiate these age groups are not provided. To create the requested dictionary, we will assume the following ranges:

- Senior: blood insulin levels above a certain threshold (e.g., 10.0)
- Adult: blood insulin levels below the threshold

Here is the requested dictionary:

```json
{
	"Adult": [5.1, 5.6, 6.2, 8.3, 9.5],
	"Senior": [10.2, 11.5, 12.9, 13.7, 15.6]
}
```

Please note that these values are just hypothetical examples, and the actual ranges for differentiating between senior and adult age groups may vary based on the specific dataset and analysis.
