|Springbok mantis ootheca|
|New zealand mantis ootheca|
The ootheca on the left is from a springbok mantis, the one on the right is from the new zealand mantis - Orthodera novaezealandiae. A careful poke about in the bushes around where the anomalous oothecas were deposited finally yielded my first sighting of the new zealand mantis.
All of these mantises are young, about 1.5cm in length. Full grown adults have wings and get up to 4cm in length.
The introduced springbok mantis and the natve new zealand mantis are the only two mantises living in New Zealand.
