Eine Mücke 'sticht' (stings/bites); it does not 'beißt' (bite). The verb 'beißen' is used for animals with teeth. This mistake is very common among learners.
Ich wurde gestern Abend von einer Mücke am Arm gestochen.
I was bitten by a mosquito on my arm yesterday evening.
Mosquitoes are known for 'summen' (buzzing) and 'stechen' (biting/stinging) people. To protect yourself, you use 'Mückenschutz' (mosquito repellent/protection) or a 'Mückennetz' (mosquito net).
Das Summen der Mücke hat mich wahnsinnig gemacht.
The buzzing of the mosquito drove me crazy.
In Austria and parts of southern Germany, the word 'Gelse' is often used for 'Mücke' (mosquito). Both words mean the same insect.
Mach das Fenster zu, sonst kommen die Gelsen herein!
Close the window, otherwise the mosquitoes will come in!
The idiom 'aus einer Mücke einen Elefanten machen' (to make a mountain out of a molehill, literally 'to make an elephant out of a mosquito') is a fixed structure. The verb 'machen' (to make) is conjugated and adapted to the person in the sentence.
Reg dich nicht so auf, du machst schon wieder aus einer Mücke einen Elefanten.
Don't get so upset; you're making a mountain out of a molehill again.

'Fliege' and 'Mücke' are both small flying insects, so they can easily be confused. A 'Fliege' is often seen near food or garbage; it is annoying, but normally does not bite. A 'Mücke' is especially known for biting people or animals and making the skin itch afterward. If an insect is just flying around and lands on the table, you are more likely to say 'Fliege'. If it buzzes at night and bites, you say 'Mücke'.
