Empusidae

life science Maturity 5-7 Next article →

Empusidae is a family of mantises that mimic plants. These insects are known as ambush predators. This means they wait silently for prey to arrive. They use their unique shapes to hide in plain sight. Most species live in Africa. You can also find them in Southeast Asia and southern Europe. They are a monophyletic lineage. This means all members of the family share a single common ancestor.

The bodies of Empusidae are quite bizarre. They are relatively large insects with strange shapes. The prothorax is always surrounded by a crest. The pronotum, which is the part of the body behind the head, is characteristically elongated. Many species have a lobed abdomen. Their middle and hind legs often have flap-like appendages. These parts help them blend into their surroundings. This physical structure supports their life as ambush predators.

These mantises have specialized organs for survival. Members of the Mantoidea superfamily possess a cyclopean ear. This ear is located on the metathorax, which is a section of the thorax. This organ is an adaptation to avoid being eaten by bats. Scientists believe this adaptation originated in the early Eocene. Their mouthparts are also specially adapted. They use these parts to feed on other insects and small animals.

Scientists have a long history of studying this group. The species *Gongylus gongylodes* was the first mantis ever described. It was named by Linné in 1758. Because *Gongylus* mantises are often bred in captivity, we know much about them. We understand their breeding preferences and their behaviors. For example, they have a specific defensive behavior. They create a hissing noise to scare threats. They do this by rubbing the serrated edges of their front wings against their hind leg femurs.

Taxonomy helps us organize these insects into groups. The Empusidae belong to the superfamily Hymenopoidea. This superfamily also includes the Hymenopodidae family. Phylogenetic studies show that Empusidae is a sister group to Hymenopodidae. Together, these two groups are sister groups to all other ambush mantises. The current classification includes ten different genera. There are about 28 species within the family. A major revision of this classification was published by Svenson et al. in 2015.

The family is divided into two main subfamilies. The first subfamily is Blepharodinae. This group includes the genera *Blepharodes* and *Blepharopsis*. The second subfamily is Empusinae. This subfamily is more complex and contains two tribes. The first tribe is Empusini. It includes several subtribes like Empusina and Idolomorphina. The second tribe is Idolomorphini. This tribe includes the genus *Idolomantis*. Each group is defined by specific evolutionary relationships.

Humans have been aware of these insects for a very long time. In Iran, there is a site called Teimareh in Khomeyn County. This site contains ancient rock art. Researchers discovered a rock carving of an Empusidae there between 2017 and 2018. The carving shows a mantis with raptorial forearms. This insect-like image is 14 cm long and 11 cm wide. It features two circles at its sides. The carving may be between 4,000 and 40,000 years old. It is similar to the famous 'squatter man' petroglyphs found worldwide.
