Deroplatys desiccata

Deroplatys desiccata, known by the common name giant dead leaf mantis, is a praying mantis from Southeast Asia. This is the type species of genus Deroplatys. D. desiccata takes its common name from its resemblance to dead, leafy vegetation including having a flattened, greatly extended thorax and "intricate leaf patterns" on its wings. This insect varies in color from mottled brown through "pale orangey brown" to a very dark brown that is almost black.
This creature's camouflage is aided by its movements as well as its appearance. When disturbed, it rocks gently as if caught in the breeze. When threatened, it typically falls to the ground and lies motionless. It can also react with a threatening display consisting of "black underwings splayed out, with large eyespots, frightening away unsuspecting predators."
The intricate lines on the mantis' body, which serve to look like the natural veins on a leaf, as well as its dark brown colors, are beneficial to the species as it has been shown to avoid the attention of aerial predators or other insects.
As its common name indicates, D. desiccata is larger than other species of dead leaf mantis. Females grow to 75–80 mm... Wikipedia →

Rare
Under 5% of wildlife watchers report a Giant Dead Leaf Mantis sighting in Singapore on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 847th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Giant Dead Leaf Mantis in Singapore on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Giant Dead Leaf Mantis sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Giant Dead Leaf Mantis sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Giant Dead Leaf Mantis is recorded against all the insects logged in Singapore (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
