Bush Katydids - Subfamily Phaneropterinae


This page contains pictures and information about Bush Katydids in Subfamily Phaneropterinae that we found in the Brisbane area, Queensland, Australia.

Nymph body length 10mm 
Phaneropterinae is the largest subfamily of Tettigoniidae. They can be found in different kinds of habitats. They are common in rainforest and eucalypt forests. All of them are herbivorous. Most of them feed on a large variety of plants, however, many species show their hosts preferences. Most of them are active at night although a few are active during the day. Most species are found on trees while some are found on grasses and others on ground. 
Nymphs are usually looked different from their parents. Most nymphs take the advantages of mimicking other insects to avoid predators. Most adults, however, are green in colour and camouflage as leaf. 
Bush Katydids in Subfamily Phaneropterinae have the globular head. Most species females have short and armed ovipositor which cut the edge of leaves where hard hard, black, disk-like eggs are laid. Some other species glue their rows of eggs on twigs or bark. A few species lay their eggs on ground.
As the katydids, males sing with very complex songs. In some species, females may reply to males' songs.  

Tribe Ducetilli

Brown-backed Bush Katydid
 DSC_3431.jpg (103037 bytes) wpeE.jpg (24447 bytes)
Ducetia japonica, Female, male, body length 30mm, nymph body length 20mm
We found this green katydid nymph on a small tree top during winter at Toohey Forest. It was moving slowly trying to escape from our disturb. The nymph was leaf green in colour and did not have any marking or pattern on its body. Its wing buds were well development showing it could be the last instars, but relatively small in side. Later we found an adult which we believed they are the same species For more information please also check this page.
White-backed Katydid Nymph
DSCN7561.jpg (272212 bytes) wpe17.jpg (26532 bytes) DSC_0293.jpg (207367 bytes) 
? Ducetia sp., nymph, body length 20mm  
Pictures taken during mid summer in Karawatha forest. We encountered this nymphs many times, but does not know how its adults look like. This could be the nymph of the above species. More pictures can be found in this page.

Tribe Phaneropterini 

Naskrecki's Bush Katydid
32-Spotted Katydid,  Mottled Katydid,  Speckled Grasshopper
wpe8.jpg (31035 bytes) DSC_3489.jpg (252530 bytes) wpe1.jpg (35238 bytes) 
Ephippitytha trigintiduoguttata, male, female body length 65mm, nymph body length 20mm
This large katydid is quite common in Brisbane bushlands. We sometimes found this katydid in our backyard. Males and females look almost the same. However, nymphs look very different. More information and pictures can be found on this page
Speckled Katydid
PWC_9906.jpg (141631 bytes) DSC_4861.jpg (255834 bytes) PWC_9766.jpg (215609 bytes)
Diastella latifolia, adult body length 35mm, nymph 15mm. 
The katydid looks similar to those Caedicia species below, although it has the stout body and shorter wings. We found this species once in Ford Road Conservation Area late summer Jan 2009. The katydid was wandering on grass near the forest floor. It was slow-moving, although it did jump and fly to a meter away when we came too closely.  Please also check this page for more pictures.
Common Garden Katydid
DSC_9057.jpg (235157 bytes) 
Caedicia simplex, nymph length 25mm 
Pictures was taken on Oct 2007 in Karawatha Forest. From the reference information, the Common Garden Katydid broadly occurs throughout the temperate areas of east coast of Australia. However, in Brisbane we found they are not quite common. The Common Garden Katydid is hardly seen. 
? Common Garden Bush Katydid
DSCN6501.jpg (310366 bytes) DSCN1616.JPG (61632 bytes)
? Caedicia simplex, body length 20mm  
We think this could be the Common Garden Katydid nymph. We will try to raise one large nymph to adult next time if we find one. Please come back to check this page later.
Brisbane Garden Katydid
wpe6.jpg (24028 bytes)
Caedicia sp., male, female length 40mm, nymph length 25mm
Brisbane Garden Katydids, as its common implied, are common in Brisbane gardens. The insects are green in colour resemble leaves. On the top of their abdomen there are the pink and yellow pattern covered by their wings. More information and pictures please click here.
Dark Green Katydid
DSC_7493.jpg (305971 bytes) DSC_7488.jpg (340320 bytes)
? Caedicia webberi, body length 35mm
This katydid look very close to the species Caedicia webberi, but the species is a rainforest species and found only in northern part of Queensland. Please check this page for more pictures and information.
Unknown Bush Katydid Nymph I
DSC_0508.jpg (292279 bytes) DSC_8864.jpg (277631 bytes) DSCN1555.JPG (55348 bytes)
? Caedicia sp., nymph, body length 25mm, 15mm
We found this nymph many times but did not known their adult forms yet. Next time if we found some last instars we may keep them to see what the adults look like, We think it could be the Brisbane Garden Katydid nymph but not exactly sure. Details information can be found in this page.
Unknown Bush Katydid Nymph II
DSCN0636.jpg (148472 bytes) DSC_7408.jpg (298636 bytes)
? Caedicia sp., nymph, body length 5-10mm
Those katydid nymphs are the 1st and 2nd instars. They could be the 1st and 2nd instars of the Brisbane Garden Katydid above. Please check this page for more photos.
Small Grassland Katydid
wpeF.jpg (45191 bytes) wpe1B.jpg (37048 bytes)
Polichne sp., head to wings tip length 30mm
Pictures taken in Mt Cotton during mid summer. This katydid is relatively small in size. The brown form was found in Alexandra Hill during later summer. More pictures and information please visit this page.

Unplaced Group

Gum Leaf Katydid
Torbia viridissima, female length 60mm, nymph length 30mm, 20mm. 
This katydid resembles a gum tree leaf. We found it feeding on a gum tree at night in Wishart in late summer. Notice the openings on its front legs. They are the hearing organs function like our ears. The female katydid uses them to locate the males by their love songs. We have more information about them on this Gum-leaf Katydid page.
Mountain Katydid, Mountain Grasshopper
DSC_4013.jpg (200664 bytes) wpe15.jpg (59789 bytes) wpeA.jpg (43606 bytes)
Acripeza reticulata, body length male 40, female 30mm, nymph 20mm
Mountain Katydid is one of the Australian Insect Icon because of its remarkable colours. In normal, the insect is well camouflage as dry leaf in dark brown colour. The katydid doesn't show her colours unless she is disturbed. Then she raises her pair of wing-covers and exposes the bright red, blue and black striped abdomen.
