Mantis female
Here’s something you don’t see that often: a female praying mantis extruding her egg case. I have never seen this happen before, although our house has quite a few old empty ones crusting up the paintwork. Bella and I will be able to keep an eye on it for the emergence of the mantis infants, although I’m going to have to do some research to see how long that will take.
Apparently this, our native mantis, is being displaced by an introduced species of mantis from South Africa. Maybe they haven’t reached Wellington yet, as I have only see this variety.
I was also a little concerned later this afternoon to see a tiny fly with a large ovipositor clambering over the now hard case. I wonder if mantises have their own parasitic wasps? I hope not. I love those wee mantis babies.
Updated, May 2009: I have recently discovered another female praying mantis depositing her egg sac (otherwise known as an “ootheca”), this time on our car. In addition, I have some more mantis photos.

The one in the picture is the New Zealand Praying Mantis, Orthodera novaezealandiae. I think there’s a very similar Australian species though, which will be the one you’ve found.

How cold of temperature can a praying mantis handle… the temps have been dropping to 38-40 at night… they are still alive outside but should I bring them in and put them in separate containers.. they are both females… living on separate bushes… I don’t want them to freeze to death…

New Zealand Praying Mantis Adult insects lenghts are Males 35mm Female 45mm.
Predacious, catches insects up to as large as itself.
NZ Praying Mantis have a bright blue patch inside front leg and is distinctive
Adult insects usually sit on top of leaves
They enjoy tempertures of between 25-30 degrees.
New Zealand mantis are generally larger and a darker green than the African species and make a much tidier more compact egg case.
Between the two large bulging eyes on their head are three more eyes,and they have a single ultrasonic ear between their back legs.
The female of the species can fly, and, contrary to popular belief, rarely eat the males.
One individual can eat up to 20 flies in a day, snatching them from the air in one twentieth of a second with their extendable front legs.
They rarely survive the winter, unlike the African mantis which can.
For this, and other reasons, the African mantis is considered a potential threat to the survival of the New Zealand species.
Mating occurs and eggs are produced in the autumn. Although the female of some species of praying mantises is known for eating the head of its mate after copulation, this rarely occurs in this species and when it does, it may be an artifact of captivity. The egg sacks (oothecae) are deposited on flat open surfaces between Febuary and continue through to April . Laying can take between 3-5 hours. The female produces between 2-5 egg sacks which hold between 5-70 eggs each. The mantis passes the winter in the egg stage and is triggered to emerge by warming spring temperatures. When the nymphs emerge in the spring, all the hatchlings hatch within 11 days of each other. Nymphs pass through six stages (instars). Each stage lasts between 10-15 days and it can take between 3-6 months before the mantis is mature.
Adult Mantis live for 7-9 months
NZ Mantis were once found throughout NZ except west coast and Stewart Island. They are again spreading away from native Auckland and are now found in Wellington and sometimes down to Christchurch.
Maybe they are running from the South African Mantis. Anyone Know?
Where are they seen ?

I saw a praying mantis, that is a bright green with a brown underbelly. I couldn’t tell if it was pregnant or wound. I thought eggs were coming out from the side. But when the eggs fell to the ground they moved around like maggots but were thicker and a yellow color. Anyone know what it could be?

Do young preying mantis’ that just hatched survive in cold weather ie: winter temps or lows in low 40/30s.

Kyle: I’m not sure – but I wouldn’t think so if you are, as I am guessing, in the Chicago area. Further south in the States they might.

i recently caught a mantis.. and the next morning she laid eggs?? what do i do now?? do i have to keep her in a cage 0r do i keep them apart?.. HELP ME PLEASE…
john

tony, it really depends where you live. If it is a new zealand mantis the female will die otherwise if it is a different species you might want to find out if they can live throuhg the winter. if they can you might want to seperate them as sometimes they will eat their omn offspring.

Hi michelle, I would think that you are bringing the egg cases inside on something they have been layed on. Do you see the big ones outside? Are they all green or some brown? The native one is not brown and has a blue patch on its front legs. If they aren’t the native one, they may be coming inside and laying. Or the babies are running up the outside and into an open window. If they are native, please put them carefully outside. Good luck.

I’ve seen the female mantis extruding her egg case many times and then in the spring I’ve witnessed the emerging young. But what I’ve never seen is a mantins in winter. A few weeks ago around the beginning of July in Johannesburg, I rescued a very slow and cold mantis one morning from my garden wall. I brought it inside and put it on my kitchen windowsill and it’s been living there ever since. Because there are no insects around now I’ve been giving it cat food every few days, which he seems to like and also spraying him with water. Can you explain this, is it an unusual ocurrence?

Here’s an update on my rescued mantis, who I’d been referring to as “he”. Well he turned out to be a she, because last night she extruded her egg case. As we are in the Southern hemisphere this usually happens around April and in September the young normally emerge. I assume she won’t live much longer, but she’s given me her young to look after!

I live in W.V. and about once a year a mantis will land on my outside of my house but, I can’t figure out if it’s a male or a female. I’m assuming it’s a female because it is rather large. It’s bright green with just a touch of brown on it’s underbelly . I am half Indian and was alway’s told it was a sign of good luck to have a Mantis “visit” you. I just want to know how to tell what’s the sex?

the way to tell the sex is start at the back legs and count the square things down to the bottom of butt. the males have 6 and the females have 8

my mantis layed her egg sack 4 days ago. I was told she will die soon. She had eaten 3 crickets since the birth. I hope she will not die she is beautiful. I hope you have good news for me. I will be waiting for you reply.
Thanks Colleen

Colleen, Whether your mantis dies soon or not really depends on how old she is. A female can lay more than one ootheca in her lifetime. It is, however, October and if you are in the northern hemisphere then probably your mantis is close to the end of her natural lifecycle. HOWEVER, I have about 15 mantids right now and they are all of varying ages. A couple are relatively young still, so who knows? It sounds to me like her appetite is still pretty good, which is definitely a good sign. I have noticed they tend to shy away from food in their last days. Also, does she show many signs of aging (spots, stress, etc.) or having laid egg sacs before? This may be hard to tell if you haven’t had much experience with mantids before. They sure are fun! I have a very cute little male sitting on my laptop while I type right now!

We have been keeping Mantises for around two years now. We have found that feeding them keeps them alive. I expect they die off “in the wild” when food becomes hard to find. We have had a couple live for well over a year with multiple egg sacs. What we find hard is what to feed the little babies.
