Dysdercus decussatus, the fork-banded cotton bug, is a species of true bug in the family Pyrrhocoridae and genus Dysdercus. Dysdercus decussatus is a medium-sized bug with a body length of 11–16 mm. It features a distinctive red body with black legs and a head that can be either red or black. The forewings display a prominent X-shaped or fork-like white band, which aids in distinguishing it from similar species in the region. Nymphs are characterized by a black head. It is also known regionally as the "Cotton Stained Bug" or "Cotton Striped Bug."
This species is widely distributed across tropical South and Southeast Asia, from Sri Lanka to the Malay Archipelago, as well as New Guinea, northern Australia, and several Pacific islands. It also occurs in adjacent temperate regions such as northern China and Japan. In Taiwan, its distribution is limited to the southern regions and Lanyu Island.
Dysdercus decussatus is commonly found in groups under leaves or among the flowers and fruits of host plants such as those in the genera Hibiscus and Thespesia. It prefers tropical and subtropical environments, often associated with coastal or agricultural... Wikipedia →

Rare
Under 5% of wildlife watchers report a Dysdercus decussatus sighting in Hong Kong on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1005th most-seen of the 1125 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 Dysdercus decussatus in Hong Kong on a given day, so our monthly data shows no clear season.
2nd of 2
Of the 2 cities where we can rate Dysdercus decussatus sightings, Hong Kong ranks 2nd at under 5%. The best odds are in Singapore (Singapore, about 10%).
GBIF citizen-science records
It is estimated from how often the Dysdercus decussatus is recorded against all the insects logged in Hong Kong (6 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.
