Your answer to the previous question was that your insect did not have the following characteristics: slim and rather similar in appearance to a moth; long, hair-like antennae; and silky hairs that cover its wings and body.

Does your insect have antennae that are either very short or not noticeable at all?

Look at your insect’s antennae. By “short antennae,” this question means antennae that are less than a one-fourth of the length of the insect’s body (see the illustration).
