lol..
I've only ever found 2 or 3 full grown mantis around here.. Never had seen an egg case before I ordered them off eBay.
I got 2 Asian and one European eggcase.
The European mantis are little badasses! Much more aggressive than their Asian counterparts. They'll chase the asian ones around, lol...
Wow, that is cool...I don't know if Hawaii would take to kindly though with me importing Mantis eggs
Heh.
I am sure Hawaii has some species of mantid. There are an estimated 1500 - 2200 different species of mantids with the common estimate around 1800. The greatest diversity is found in the tropical regions. Africa supports some 880 species, Asia 530, Oceania 165, the Americas 410, and Europe 24 species. In North America there are 20 species, 8 of which are in Arizona. :Q
They're really cool bugs. Scientists don't even know what class to put them in, so they get their own. They have large, compound eyes, which help give the mantis good eyesight, but it must move its head to center its vision optimally, much like a us. This has been an area of considerable scientific research. They have shown that a motion parallax is apparent in the mantis. By moving its head, it measures the distance between itself and another object. It measures an object's movement relative to its background, to gauge its distance. They have shown that this only works when both eyes are functioning. The use of binocular triangulation in relation to distance is seen as proof of stereoscopic vision, a feature normally only seen in vertebrates. :Q They are able to rotate their head 180 degrees, and visually scan a total of 300 degrees.
Ears occur in 60% of mantids, and are found on the underside of the mesothorax. The mantis is an auditory Cyclops, and having only one ear is a feature unique to the mantis, not seen anywhere else in the animal kingdom. The ear is a deep 1 mm slit that has cuticle knobs at either end and two eardrums inside. It is located in the ventral midline between the metathoracic legs. Interneurons in the metathoracic ganglia mediates hearing. The ear is tuned to ultrasonic frequencies of 25-60 kHz, with thresholds of 55 to 60 decibels. This is the range of bat's echolocation, supporting evidence that mantids, like lacewings, moths, and crickets, use hearing as a defense against predators.
They have been documented eating 21 species of insects, soft shelled turtles, mice, frogs, birds, and newts. :Q
