Perginae larvae batch 5
Workbook
This is the fifth collection of Perginae larvae which I am aiming to rear through to adult stage.
My goal is to obtain female Perga dorsalis adults for COI barcoding in order to determine whether Perga dorsalis and Perga affinis individuals identified morphologically have different barcodes.
Collection of larvae at home, December 6th
On 20th November we spotted a clutch of 12-13 Perginae larvae in an upper branch of the same eucalyptus sapling (probably E. globoidea) from which we collected the clutch 4 larvae. At the same time, I saw a clutch of 5 larvae in an Allocasuarina sapling immediately behind the eucalypt sapling. See photos below.
As we were just about to head off to Yamba, we decided to collect these only after we returned home.
On arriving home on 2nd December, initially we couldn’t find these larvae. However, I sighted 3 again on 5th December, high up on the trunk of the sapling. A corpse of a larva was in the Allocasuarina sapling.
We collected these larvae and transferred them to a metal cage. They grouped together quickly and began feeding on the vegetation on their branch.
Kerri found another larva (shown below) high up on the trunk of the same eucalypt on 6th December. We added it to the other 3 larvae.
8th December, morning
All 4 of the larvae have come together in a single cluster on a leaf. They have been feeding actively as evidenced by the bite marks on the leaf and the amount of frass in the bottom of the cage.
This is a workbook page … a part of our website where we record the observations and references used in making species identifications. The notes will not necessarily be complete. They are a record for our own use, but we are happy to share this information with others.
