...the very real possibility LEDs used in Day/Night cameras also emit in other parts of the spectrum that would cause bugs to be attracted to them.
Alain, actually your graph does not support such an inference. The reason is simple, if the illuminator was to emit any visible light, besides the dull glow of near infra-red, than that would be, ahem, visible.
Therefore I assume you mean UV or shorter wavelengths. More promising perhaps but with the exception of the mecury vapor lamp, all other light sources, including LED types, are shown by your own graph to have a single range of spectra values. Even in the case of mecury vapor lights (which use a completely different method of generation) which has various discrete frequencies, there is no gap bigger than the one from blue to green.
Unfortunately for what you are saying to be true the LEDs would have to generate copious amounts IR without generating the entire visible spectrum, only to resume in the UV range once again.
Furthermore, white LEDs lamps are actually not white, they must use various combinations of differently colored LEDs together with reflective coatings to approximate white. As infrared LEDs are under no such requirement, all of the LEDs woukd be of the same approximate wavelength, and if they were on your chart the would look much like the mercury lamps, only with a single spike.
Therefore it seems highly implausible that the IR LEDs would give off any significant UV.
