Family Amorphoscelidae
- This page contains pictures and information about Spiny Bark Mantids that we found
in the Brisbane area, Queensland, Australia.
-
 - Female, body length 25mm
-
- Spiny Bark Mantid has prominent short spines on the head and pronotum. They
are very hard to find for they are very well camouflaged. We found them a
few times in different Eucalypt forests around Brisbane.
-
 -
- There are two known species in genus Gyromantis, the G. kraussi and
G. occidentalis. The later only found in north of Western
Australia. So we believed the species we found in Brisbane is the G. kraussi.
Nymph
  - Male body length 20mm
-
- Later in the end of the summer, in Alexandra Hill on a large gum tree trunk.
we found this silvery-grey Bark Mantid. This mantid has larger developing wing
buds, i.e., it could be the male nymph.
-
  -
- This mantid has pinkly-red patches on inter forelegs.
 - Female body length 20mm
-
- Another Spiny Bark Mantid found in Karawatha Forest. This one has smaller
wing bud but larger abdomen. We believed it is a female.
-
Female Adult
 -
- Hunting on gun tree trunk. This mantid is slow moving even when disturbed.
-
 -
- This female adult has the fully developed wings, although too small for
her to
fly. In this Bark Mantids family only male can fly.
-
-
- Female lay eggs in oothecae, which is
long and narrow and is attached to tree trunks.
 -
 -
Male Adult
 - Body length 30mm
-
- Adult males are fully winged. They are even harder to find. We found the male
only once in Karawatha Forest. It was hunting on a large smooth bark gum
tree trunk. It was late summer Feb 2008.
