This is a sign of good luck for yours truly, dahling. It's also a reminder to mediate and contemplate.
Here's the message of the mantis, according to symbolism guru, Avia Venefica:
The mantis comes to us when we need peace, quiet and calm in our lives. Usually the mantis makes an appearance when we've flooded our lives with so much business, activity, or chaos that we can no longer hear the still small voice within us because of the external din we've created.
After observing this creature for any length of time you can see why the symbolism of the praying mantis deals with stillness and patience. The mantis takes her time, and lives her life at her own silent pace.
These traits have lead the mantis to be a symbol of meditation and contemplation. In fact, in China, the mantis has long been honored for her mindful movements.
The mantis never makes a move unless she is 100% positive it is the right thing for her to do. This is a message to us to contemplate and be sure our minds and souls all agree together about the choices we are making in our lives.
Overwhelmingly in most cultures the mantis is a symbol of stillness. As such, she is an ambassador from the animal kingdom giving testimony to the benefits of meditation, and calming our minds.
An appearance from the mantis is a message to be still, go within, meditate, get quiet and reach a place of calm. It may also a sign for you to be more mindful of the choices you are making and confirm that these choices are congruent.
