The heart of your belief - that humans are unnatural, and insects are not.
Insects can die by the millions in a city and not affect the area nearby. Yes, Florida is a good test case - rural Florida has no shortage of insects in spite of large cities with lots of lights.
If you want to run around naked in a swamp at night so as to be a part of the ecosystem, have a nut. I think you will find the insects call you 'dinner'!
I would love to see you data showing most crime occurs during the day. Pickpockets? Yes. Armed assault or house robberies? Show me the data.
People put lights up along city streets to make it safer to drive. Your headlights illuminate your immediate path, but you cannot see stuff that might be moving in to it without extra light.
Over 80 per cent of home burglaries occur in daylight. These crimes are most often committed by young men between 16 and 25 years of age.

Most crimes against the elderly were more likely to occur in or near their homes, and to occur in daylight hours.

These numbers indicate that more juvenile crimes occur by day than by night.

Most crime, especially domestic break-ins, occur in daylight, proving that light can aid criminals.
The Association of British Insurers do not recommend outdoor lighting as a crime deterrent. Indeed, insurance companies do not offer a reduction in your premiums if you have “security” floodlights, due to the lack of evidence to suggest that lighting reduces crime.
Measures such as CCTV, increased street lighting and longer custodial sentences were judged in the report to have been expensive failures, with only a few exceptions.”
When lighting was increased in Chicago “...there was a 21 percent increase in reported evening incidents that occurred in alleys”
…. And so on….
Bjornskau, Fosser, and Sagberg (1999) report that when drivers feel safer through improved street lighting they gain a sense of false confidence. They no longer drive according to the conditions. The seem to think that because lighting gives them increased visibility, they can drive faster with reduced concentration. Any perceived advantage of having street lighting is therefore nullified and the incidence of accidents in illuminated areas may well increase. Street lighting, therefore, does not necessarily improve road safety, and may actually make it worse.
