Wow! Its really easy to miss. Given its strange position (on an antenna), this could just be an insect using the moth as a perch (or maybe for transport - a relationship called phoresy) rather than a parasite.

Thanks Jonathan, my thoughts were that it was perhaps providing a cleaning service much like Remora on shark or Plovers that clean crocodile teeth etc...an acceptable service provider. The moth didn't seem perturbed by its presence anyway.
...Is it White Ermine ?
Great shot of two species,yes its a White Ermine the yellowy colour indicates a female,see my photo above in other observations.The smaller insect looks like a greenfly perhaps.
The 'parasite' appears to be a mosquito of some sort, either a male or freshly-emerged female from the colouration, and is likely to have been attracted to the window in the same way as the moth, rather than feeding on it
