Scientists believe that unlike the males of most species of moth, the male whistling moths of Nambung, Australia, call female moths to them by the use of acoustical signals, but not olfactory ones, and they attract their mates during the day, rather than at night.

another reason why choice (a) is incorrect is its use of "by the use of..." SUBJECT + ACTIVE VERB + BY + NOUN is generally incorrect.** SUBJECT + ACTIVE VERB + BY + VERBing is generally correct, if "VERBing" is the method or process by which the ACTIVE VERB is carried out. e.g. i prepared for the test by studying flash cards --> CORRECT i prepared for the test by the study of flash cards --> INCORRECT on the other hand, SUBJECT + PASSIVE VERB + BY + NOUN is an absolutely fundamental form, if the NOUN is the thing/person that did the action to the SUBJECT. e.g. james was seen by two witnesses. --> CORRECT

In A, the phrase by the use of is unnecessarily wordy, and the insertion of they is not required. D and the前后rather 还平行了

The use of but not does not clearly convey that most other moths use olfactory signals; rather than" would be preferable, as well as parallel to rather than at night.

这里they与前面都主语相同，能省就省。而且加上之后由于前年没有加上引导词they导致局为这个句子的平行结构发生变化，直接与scientists平行了。 不优。

这题目了有but，有了and，考平行。 先把句子的结构拿出来看。 S believe that ..., the MW call female to them by the use of A, but not B, and they attract their mates... call , and they attract 不平行。

1. OG解释the use of 不能很好表达出most species of moth是通过using acoustical signals来吸引的，the use of 强调的是use，不是signals。并且我觉得but not后面为了平行，用the use of olfactory ones会好一点。 2. but not用rather than代替的话，则使得call...与attract...两个句子平行的工整一些。
