Environmental conditions

The ideal temperature for the Budwing mantis is about 26 ° C, but between 24 and 30 ° C it feels good too. At night you can let the temperature drop to around 18 ° C.
This species does not have high demands regarding the air humidity, but it is important to spray about two or three times a week to allow it to drink. A target air humidity is about 50% in a place with lots of ventilation.
As with all types of praying mantids, this species needs a cage of at least 3 times the length of the animal in height, and at least 2x the length of the animal in width. For an adult female this means at least 21 cm in height and 14 cm in width. A nice size for a terrarium would be 30 x 20 x 30 cm (hxwxd), so there is room for lots of fake plants and perches. Bigger is always better.

Breeding the Budwing Mantis

The budwing mantis can be bred pretty easily if taken proper care of them.

First you need to get an adult pair of a male and female mantis. Luckily it’s easy to see the difference with the Budwing Mantis. The females of this species are larger and wider than the males, this can already be seen when they are still a nymph. You can also use the Segment Counting Sexing Method. If this species reaches maturity, it can be seen in a glance which one is the male and which one is the female. Females are really big with short wings, while males are small and slender and have long wings.
Approximately 2 to 4 weeks after the last molt, you can introduce the male to the female. Make sure that the female eats very well before you put the male in her enclosure. The female can be quite aggressive to the male and could eat him before the mating. When the female is responding agressively to the male, it is better to remove him and try again an other time. Mating can take several hours, the male must subsequently be removed from the residence (to safe its life).
