Originally posted by gaweidert Back in 2020 I was photographing comet NEOWISE just south of Geneseo, NY. The fireflies were out in force.
I used to see that many in the back yard. Now I'm happy to see two or three blinking for a mate. Extinction - excepting a massive meteorite impact - is local. The decline isn't because of a massive event, it's because of loss of a weedy patch here, a housing development going up on several acres in the next state, a golf course "improving" some land and "getting it onto the tax rolls" One local population after another being wiped out. Little by little the milk weeds that monarch caterpillars require become harder to find, fewer in number, more widely scattered. Then there is a random event, and the small number of surviving monarchs all fail to produce viable offspring. Some monarch populations are doing OK, but overall, their numbers are down catastrophically. If you've never seen the mass gatherings of monarchs in Mexico where the eastern populations overwinter, it's worth a GOOGLE search to see some pictures.
