  • Steel-blue sawflies

    Steel-blue Sawfly larvae are also known as 'spitfires' as they can eject an irritating fluid from their mouth. This defence method ensures predators avoid them, enabling them to reach high numbers.

  • Ants, Wasps, Bees and Sawflies: Order Hymenoptera

    Ants, wasps, bees and sawflies play key roles in most ecosystems as predators, parasites and pollinators.

  • Sawflies

    Sawflies are probably closest to the ancestral form that all hymenopterans (ants, wasps, bees and sawflies) evolved from. However, they are placed in a separate suborder, Symphyta (ants, bees and wasps belong to the suborder Apocrita) based on reproductive and other characteristics.

  • Metamorphosis: a remarkable change

    Metamorphosis refers to a major change of form or structure during development. One of the most dramatic forms of metamorphosis is the change from the immature insect into the adult form.

  • Sawflies: Suborder Symphyta

    Sawflies are a relatively small group of insects. There are 176 species in Australia, including those with larvae known as 'spitfires'.

  • Wasps: Suborder Apocrita

    Wasps are a diverse group of insects. In Australia alone there are over 12,000 species, ranging from the tiny diapriid wasps, which are barely visible to the naked eye, to the spider wasps and cicada-killer wasps, capable of taking large prey. Most wasps have carnivorous larvae that feed on other insects and spiders. The adults provide food for them by capturing prey or by laying the egg on or near the food source, which might be an egg, larva or pupa of another insect.

  • Herbivory: eating plants

    Herbivory is the act of eating plants and a herbivore is an animal that eats plants. Herbivores play an important role in the ecology of any area, influencing plant communities and individual plant growth. The great diversity of invertebrate and vertebrate herbivores reflects the diversity of plants. Each plant provides a wide range of feeding opportunities and herbivores show many adaptations, like modified mouthparts and behaviours that allow them to feed on plants.
