The response given by me is correct.
What it is incorrect is to say "an bug"

[bautiordonez]

You do not say "an bug", you say "a bug". An is only before vowels. And in this case you did not used "E um", which means "it is a/an". "a bug" translates as "um inseto"

[SummerMexico]

That's what he's saying. I also wrote "It is a bug" and it was marked as wrong. The "correct" answer that Duolingo provided said "an bug" which is incorrect and should be fixed.

It's A bug

[TeacherMilena]

an bug???? please let´s correct this duolingo....

[yuleylea]

the response given by duolingo is incorrect

[LydiaDC]

IT'S A BUG, not an bug

[JerielPatrick]

Why is "It is a insect" wrong? Seems right to me.

[Elen-ka]

Because you used the wrong article. It should be "an insect".

[grihau]

É um inseto? = Ele é um inseto?

[danielmonteiro16]

You'd use the latter (mostly) when a subject was used before.

Olha essa formiga. Ela é um inseto. (Look at this ant. It's an insect)

But

O que é isso? É um inseto/Isso é um inseto (emphatic)

[HugoLopes6]

"Isso é um inseto" sounds more natural...
