Where do "new" bugs come from?

Mommy and Daddy bugs? :-)

They flew in on a jet.

They could be exotic invasives that came in accidentally through shipping channels. Around here we’re having some trouble with the Asian longhorn beetle.

This short video does a good job of explaining.

edit- The above link doesn’t start at the beginning of the video. This one does.

I found a picture online, apparently the beetles are lined June beetles, and according to Wikipedia they live in the western US and Canada. Which is definitely not here. :)

I agree with the premise that they are overseas interlopers. Here in England there are some pretty mean little buggers. Some have them have tattoos & a drug habit!!

Bugs can migrate from area to area. Bugs will lay their eggs dependent on the environmental conditions. If you’re in an area that is hot, it may not be suitable environment for this type of bug. But, because I’m not an expert, I found an article that might interest you. http://www.sciencemag.org/content/313/5788/794.abstract

Through the rift.

As well as the reasons already mentioned, climate change is shifting the territories of insects,plants and animals.

Not to mention those mutated by the radiation leak at Fukushima.

they were part of the may 21 apocalypse

@Simone_De_Beauvoir Damn, I was expecting locusts…I hear they taste great with a dash of salt.

@incendiary_dan Even if I wasn’t a vegan, gross.

@Simone_De_Beauvoir One of my professors used to say “80% of the world’s population intentionally eats bugs. 100% of the world’s population eats bugs.” Might as well go with it.

Umm, nests and older bugs. BUt I agree with @JilltheTooth ,mommy and daddy bugs.

I would go at least in part with @jaytkay. Global warming is moving the natural boundaries for some insects/animals. For instance, there are fears the box jellyfish will be prevalent in months and geographic areas outside the norm because the ocean is slightly warmer. link

@incendiary_dan I’d much rather unintentionally eat bugs.
