Third-year biology students at Linköping University arranged a weekend workshop on insect identification and DNA barcoding. The event took place on 31 January and 1 February in the Darwin and Linné laboratories at Campus Valla.
Insect identification in the lab
The main aim was to practise identification of insect orders, with a focus on Hymenoptera (wasps, bees and ants). Students worked with pinned specimens and used stereomicroscopes to study key features.
They examined:
- The narrow "waist" behind the hind legs to separate different groups.
- The ovipositor in parasitic wasps and the stinger in bees and ants.
- Antennae shape and wing structure.
The exercises were based on standard identification keys and included many individual specimens.
Introduction to DNA barcoding
The workshop also included basic training in DNA barcoding. Students used a shared spreadsheet and digital tools to register specimens and connect morphological identification with genetic data. The aim was to show how traditional taxonomy and molecular methods can be combined in current biological research.
Student initiative
The workshop was organised by Anna, Gabriel, Karoline and Oscar. Students worked in small groups and discussed difficult identifications together. The programme also included shared meals and informal discussions during the weekend.
Identification guides were available in both Swedish and English. Materials from the workshop can be used by students who wish to continue working with insect taxonomy and barcoding.
