Top 20 Most Common Insects in Australia

Ocybadistes walkeri is a butterfly from the family of the Ocybadistes walkeri (Hesperiidae). The scientific name of the species was first validly published in 1894 by Heron.

The tau emerald is a medium-sized, black and yellow dragonfly with long legs, reaching a body length of about 5 cm. In both males and females the inboard edge of the hindwing is rounded.

The orchard swallowtail (Papilio aegeus) is a swallowtail butterfly without the long tail. Despite the confusion, it is still a beautiful butterfly that is a combination of black, white, and orange. While they are typically in Australia, they are known to expand their territory to Victoria when citrus trees are abundant. This gives it the secondary name of the Large citrus butterfly.

Belenois java (synonymous with Anaphaeis java, Anaphaeis is now seen as subgenus) is a butterfly of the Pieridae family, the whites. Belenois java is scattered in Indonesia and the Australasian region. The image has a wingspan of approximately 5 centimeters in males, and approximately 6 centimeters in females. The butterfly is known as a migratory butterfly.

The wingspan is about 3 cm .

The wingspan is about 2 cm.

The false garden mantis (Pseudomantis albofimbriata) has some incredible differences between the two genders. Females are much larger but have shorter wings that make it impossible for them to fly. The males are much smaller but are able to make quick escapes given their long wings. Males also have a triangular pattern on their bodies. Otherwise, they can come in brown and green colors.

Coccinella transversalis, commonly known as the transverse ladybird or transverse lady beetle is a species of ladybird beetle found from India across southern and southeastern Asia to Malesia and Australia. It is not to be confused with Coccinella transversoguttata, a widespread species in Europe and North America also known as the transverse ladybird. The alternative vernacular of small transverse ladybird may be used for C. transversalis in instances where these two species are discussed together. The transverse ladybird was first described by Danish zoologist Johan Christian Fabricius in 1781 as Coccinella transversalis and still bears its original name. Fabricius' description predated Carl Peter Thunberg's naming of this species as C. repanda by several months. Measuring 3.8 to 6.7 millimetres (0.15 to 0.26 in) long and 3.3 to 5.45 millimetres (0.130 to 0.215 in) wide, the transverse ladybird shows little variation across its wide range. It has a black head with predominantly bright red or orange elytra boldly marked with a black band down the midline and two lateral three-lobed markings.

The spider species Plebs eburnus is commonly referred to as the eastern grass orb-weaver or the eastern bush orb-weaver, and sometimes more simply as the bush orb-weaver. It is an orb-weaver spider from the family Araneidae endemic to Australia. It was previously classified as a member of the genus Araneus but has been reclassified in 2012 into a newly described genus Plebs. It is closely related to the Western Bush Orb-weaver, P. cyphoxis. It is a very common spider with distinctive white markings (although these marking can be quite variable), which give it the species name eburnus pertaining to ivory. It is found in scrub and tall grasses where the female constructs a vertical web usually no more than 2 metres from the ground, and stays there day and night. The web of some of these spiders has been seen to be decorated with nearly vertical stabilimentum (like a clockface at 5 minutes to 5 or its mirror image). The stabilimentum of P.cyphoxis is usually observed vertical (like a clockface at 6 o'clock).

Agrotis munda is a butterfly from the family of owls (Noctuidae). The scientific name of the species was first validly published in 1856 by Walker.
