Insect diagnostic service

The South Australian Research and Development Institute (SARDI) Entomology Unit  provides an insect identification and advisory service.

Our qualified team identify insects to the highest taxonomic level for species where this is possible.

We can also give you biological information and guidelines for control.

SARDI has a collection of approximately 5,000 species of pests and beneficial insects.

This collection helps us provide rapid and reliable identification of most insects.

We offer:

  • Insect identification.
  • Insect identification + biological and management information.

Our diagnostic services are available to the public.


All prices are available on application.

Please do not send payment with your sample, unless indicated otherwise.

We will send an invoice with the result to you.

Preparing your sample

Soft-bodied insects (larvae)

Place dead larvae samples in 80% alcohol or methylated spirits.

Make sure live larvae have adequate supply of host plant material or soil.

Adult insects

  1. Adult insects (beetles, wasps, moths etc.) can be killed before posting by placing them in a freezer for a few hours.
  2. Pack the specimens into a container and use tissues to prevent damage.

Packaging your sample

Selecting a container

Put liquid samples in a container that:

  • can't be easily crushed
  • has a good sealing lid.

Small plastic vials are ideal.

Dried specimens:

  • Don't place dried specimens directly into an envelope.
  • Always pack them in a container.

Preparing your sample for delivery

You can place the container into 'Post Pack' or other suitable envelope with packing included.

Ensure you have our correct postal or delivery address.

Sending your sample

All specimens sent to us for identification must be accompanied by the Insect Diagnostic Service Specimen Form (PDF 59.2 KB).
