蟲 and むしむし Questions (Japanese)?

I wonder what you want know...

Answering the phone,we first say "moshimoshi"(もしもし）not mushimushi to somebody on the phone.

moshi means "I say" (申す、もうす、mousu) in a old fashioned way."moshimoshi" is used to say "hey,Im here".

Although 蟲 sure is an insect,It is old Kanji not to be used in everyday Kanji.It is rather 虫（むし、mushi).

There is another word むしむし（蒸し蒸し） in Japanese.　It's an adverb to mean "hot" or "humid".

Mushi means insect, bug

the original 蟲 meaning is living thing. but modern meaning is insect.

normally we use 虫 Instead of 蟲

I don't understand why you say むし twice.
