i think that's more of a species of cranefly. Daddy long legs are an arachnid, but not technically a spider, they only have a single round body and as for true spiders, they have 2 parts to their bodies. Daddy long legs do eat mosquitoes but prefer to drink juices from plants and berries.
... I don't think that's a daddy long-leg... Daddy-long legs are a breed of arachnid (spiders are arachnids too, but a daddy long-leg is not a spider). Looks awesome though... almost cute
I hate them, we get tons in our bathroom at night, they always fly into my face! D':
This is in fact a Daddy long legs.
