Lacewings are a welcome sight in gardens across Australia, where they are often encouraged to thrive due to their voracious appetite for small insects that can cause infestations. The most common lacewing in Australian gardens is the Mallada signatus, also known as the Green Lacewing, which can be found in most states and territories in spring and summer.

Green lacewings larvae eat a variety of small insects and eggs
Green lacewings (Mallada signatus) are native to Australia and can be found in most states and territories during spring and summer. They are considered beneficial insects for gardens and orchards due to their diet of small insects and eggs, which helps control pest populations.
The green lacewing larvae are generalist predators, meaning they are not fussy eaters. They feed on a variety of small insects and eggs, including aphids, caterpillars, moth eggs, scale insects, mealybugs, psyllids, lace bugs, mites, whiteflies, leafhoppers, and thrips. The larvae are particularly effective in controlling aphids, consuming up to 60 aphids per hour or 200 per week.
The larvae have two pairs of hollow jaws, which they use to grasp and suck out the body fluids of their prey. They are often called "trash carriers" or "junk bugs" because they carry the remains of their prey on their backs, using them as camouflage to hide from predators and ambush their prey. The larvae are fast-moving and voracious feeders, growing from 2 mm at first emergence to 8 mm before pupation.
After feeding for two to three weeks, the green lacewing larvae spin a silken cocoon and pupate. After nine days, an adult green lacewing emerges to start the cycle anew. The adults are bright green to green-brown, 15-20 mm long, with two pairs of wings held tent-like over their bodies. They feed mainly on nectar, pollen, and honeydew but will also consume small insects and eggs if given the opportunity.

Adult green lacewings eat nectar, pollen, and honeydew
Green lacewings are one of the most common native lacewings in Australia. They are bright green to green-brown in colour, 15-20mm long, and have two pairs of large, lacy wings. They are most commonly found in orchards, nurseries, parks, and gardens.
Adult green lacewings feed on nectar, pollen, and honeydew. They also consume small insects and eggs, but their primary diet is focused on the former. This helps with pollination in the garden.
Green lacewing larvae, on the other hand, are predators and feed on a variety of small insects, including aphids, caterpillars, moth eggs, scale insects, mealybugs, psyllids, and lace bugs. They are often used as a natural form of pest control in gardens and crops.
To attract adult green lacewings, gardeners can plant sunflowers or dill, or allow weeds such as dandelions to grow near crops. Nectar-rich flowering plants are also enticing to these insects.

Lacewings are a natural form of pest control
Green Lacewings are most commonly used in orchards, nurseries, parks and gardens. They occur naturally in many outdoor tree and vine crops and are well suited to these environments. In settings like orchards and vineyards, it is possible to establish a breeding population for long-term management of target pests.
Green Lacewing larvae prey mostly on aphids, but also attack scale insects, mealybugs, leafhoppers, thrips, psyllids, whiteflies, caterpillars, moth eggs, many other small insects, as well as mites. The larvae are fast-moving and voracious feeders; they can eat up to 200 aphids a week. The larvae are often called 'trash carriers' or 'junk bugs' because they carry the remains of their prey on their backs. They have two pairs of hollow jaws, which they use to grasp and then suck out the body fluids of their prey.
Adult Green Lacewings feed on nectar, pollen and honeydew. They are attracted to light and will often fly indoors at night on warm summer evenings. They are also attracted by planting sunflowers or dill, or by allowing weeds such as dandelions to grow near crops.

Lacewings are most common in spring and summer
The Green Lacewing is one of the most common native lacewings in Australia and can be found in most states and territories during spring and summer. They are especially prevalent in October, when the warm weather and blooming flowers provide the perfect environment for them to thrive.
Green Lacewings are generalist predators, with a varied diet that includes small insects, eggs, nectar, pollen, and honeydew. Their prey includes aphids, caterpillars, moth eggs, scale insects, mealybugs, psyllids, and lace bugs. The larvae, in particular, are known for their voracious appetite, consuming up to 200 aphids per week.
The presence of Green Lacewings is beneficial for gardeners as they provide natural pest control. Their larvae are effective in managing infestations of pests such as aphids, mites, and mealybugs. The larvae are often chosen over the adults for pest control as they are easier to handle and less likely to fly away.
To attract Green Lacewings to your garden, consider planting sunflowers or dill, or allowing weeds such as dandelions to grow near your crops. Nectar-rich flowering plants will also entice them to take up residence in your garden. However, excessive use of pesticides can be detrimental to their populations, so it is important to use these chemicals sparingly and consider adopting integrated pest management (IPM) practices.

Lacewings are sensitive to pesticides
Lacewings are a natural form of pest control for Australian gardeners. The Green Lacewing is the most common native lacewing in Australia and can be found in most states and territories in spring and summer. They are a great buddy to have in your garden as they eat other insects and keep pest numbers down.
However, lacewings are sensitive to some pesticides. If pesticides are required, always check for side-effects and select products that are least harmful to lacewings and other beneficial insects. There is little published side-effects data for the Australian lacewing species Mallada signatus. As a guide, consult the Biobest Side Effects App and refer to the side-effects reported for Chrysopa carnea, a related lacewing species.
Lacewings are used as a natural form of pest control in orchards, nurseries, parks and gardens. They occur naturally in many outdoor tree and vine crops and are well suited to these environments. In settings like orchards and vineyards, it is possible to establish a breeding population for long-term management of target pests.
Lacewings are a cost-effective and natural way to manage pests. They are particularly effective when it comes to aphids, and can eat up to 60 in an hour. They also attack scale insects, mealybugs, leafhoppers, thrips, psyllids, whiteflies, caterpillars, moth eggs, mites, and other small insects.
By attracting lacewings to your garden, you can reduce the need for insecticides and other less natural methods of pest control.
