Abstract:
[Objectives] Bait-trap method can
be used for collecting butterflies based on bait attraction, which is usually
conducted in tropical area, but no report in temperate area. To promote
bait-trap method for butterfly monitoring in more extensive area, the
feasibility of bait-trap method conducted in temperate area was evaluated. [Methods] The bait-trap method was attempted for
collecting butterflies in a site of temperate zone, Laohegou Nature Reserve,
north of Sichuan. [Results] In 13 capturing days in August of 2015 and
2016, 411 individuals were captured, 4.6 individuals per cage each day on
average, which is consistent with the data from the investigations in tropical
area. The captured butterflies belong to 40 species, in families of
Nymphalidae, Satyridae and Libytheidae. Compared to the butterfly records based
on transect surveying in Laohegou, there were 7 new records obtained in this
bait-trap surveying. [Conclusion] It indicated that bait-trap method is feasible in temperate area.
It can be an effective supplement for traditional transect surveying, and also
a new insight for the construction of long-term monitoring projects of
butterfly.
