Mantispa styriaca, the Styrian praying lacewing, is a species of predatory mantidfly native to Europe.

The adult Styrian praying lacewing is a yellow-brown color with transparent wings that have a wingspan of 35 mm (1.4 in).

Its forelegs are similar to those of the praying mantis, with the ability to seize living prey.

Once the larva starts metamorphosis, it pupates by spinning a cocoon inside the spider's egg sac, in which it stays up to 14 days before its final molting.
