Should 'windowlicker' be hyphenated?

Three species of migrant lep in the front garden today without even trying, the joy of a well-placed buddleia/buddleja (depending on whether you're an 'i-man' or a 'j-man'). Eight species of flutterby in total but the Gatekeepers refuse to join the party out front,... anti-social little bastards.

Autographa gamma and a furry windowlicker. Painted Lady and Red Admiral were, predictably, the other two,.... should you really, really want to know.
