Trichoceridiae have
* short, usually very short, A2 (half wing length in Tipulidae s.l.)
* ocelli (absent in Tipulidae)
* long antennae (usually shorter in Tipulidae)
* somewhat different wing veins other than A2, but probably with overlap between families
Most Trichoceridae fly in cold weather, while other crane flies are mostly gone after first frost.
