### Question
Among HTC Butterfly phone users, list any five devices' IDs used by females.

### Hint
HTC Butterfly refers to phone_brand = 'HTC' AND device_model = 'Butterfly'; females refers to gender = 'F';

### SQL
SELECT T2.device_id FROM phone_brand_device_model2 AS T1 INNER JOIN gender_age AS T2 ON T2.device_id = T1.device_id WHERE T1.device_model = 'Butterfly' AND T2.gender = 'F' AND T1.phone_brand = 'HTC' LIMIT 5
