The recent discovery of a species of a jumping spider at Aarey Milk Colony, 122 years after it was first spotted in Burma, now Myanmar, brought back the attention to Mumbai’s green lung.

Even as the Maharashtra government contemplates changing the land-use of the colony from a no-development zone to a commercial zone to allow infrastructure projects such as the Metro car-shed and stabling lines for the Metro III (Colaba-Bandra-SEEPZ) project, here’s a look at Aarey’s biodiversity:

1. On Monday, an independent researcher and wildlife photographer, Rajesh Sanap, photographed a male specimen of the jumping spider, which was first found in 2015.

At that time, it was not clear if it was rare species. During surveys in 2016, a female spider of the species was found in the same locality.

The species has now been identified as Piranthus decorus, last seen in Burma in 1895. The results have been accepted for publication in Acta Arachnologica, a Japanese journal of Arachnology (study of spiders) and will be published in August issue of the journal in this year.

Aarey’s current biodiversity
77 different avifauna (birdlife) species 90 different types of spiders 5 species of Tarantula6 species of scorpions86 species of butterflies – Plain tiger, striped tiger, common crow, chocolate pansy, common mormon to name a few6 species of venomous snakes Caeciliaus, rare amphibian discovered at the interiors of Aarey colony10 rarest species of birds found in Aarey –HoopoeIndian RollerIndian BlackbirdGrey HornbillChestnut trail StarlingsRosy StarlingsGlossy IbisLoten’s SunbirdSpotted OwletsOrange headed ground thrush

A Swedish arachnologist, Tamerlan Thorell, spotted the species in Tharrawaddy, Burma (then part of British India). Jumping spiders comprise 13% of the global spider diversity and family Salticidae under which they are classified is the largest family of spiders.


“There is immense scope for research related to wildlife and environment at Aarey Colony and the list has just started being collated. The state government needs to realise that changing the land use of this green lung will severely dent the possibility of safeguarding this biodiversity. If development activities are allowed, it might be destroyed forever,” said Rajesh Sanap, independent researcher and wildlife photographer.
