Large Brown Mantid - Archimantis latistyla
This page contains information and pictures about Large Brown Mantids that we found in the Brisbane area, Queensland, Australia.
They are also know as Stick Mantis. This Praying Mantid is common in Brisbane. We can find them when they are hunting other insects among plants. This mantids is pale brown in colour and looks like a dry leave among the grass. There are two black dots on each side of its forewings. Females have half length wings which cover half of her abdomen. Males are smaller in size, have full length wings.
The Praying Mantid eggs are suffered from parasitise by Parasitic Wasps. The small holes (second picture above) were made by those wasps when they emerged.
Mantids Hatching from Ootheca
On a late winter we found a newly made Ootheca on a plant. There were two Parasitic Wasps (Podagrion sp.) trying to insert their eggs into the Ootheca. The two wasps are black in colour with body length about 5mm. They both had the very long ovipositor, more than three times of their body length. The two wasps flied away before we pointed our camera at them.
Anyways, we took the Ootheca back home to see what would happen. About three weeks later, we saw many young mantids emerged from the Ootheca. They came out one by one, look like a small worm, 10mm long and pale brown in colour. They had the first moulting immediately outside the Ootheca. Then their appearance become exactly like their mother, except much smaller. In the about picture you can see many empty skin cases left after their moulting. Watch more carefully you can see one young mantid just emerging and few others still struggling in the moulting process.
There were about a hundred of young mantids emerged. Some rested on the plant and some actively ran around. We did not see any cannibalism, could be they were not too hungry yet. After watching them for two days, seemed no more interesting things will happen, we put them back into our backyard.
Beside the the emerged of the young mantids, we also see a few parasitic wasps came out. They came out by making a small hole on the side of the Ootheca. They look exactly as the two wasps that we mentioned above except none of them had the long ovipositor. We might see the male wasps emerged only. As their mothers, they flied away quickly and, again, we failed to take any picture of them.
