cockroach appreciation time!

a big and beautiful Blaberus giganteus seen in Costa Rica. I removed it from someone else’s cabin, and it posed nicely on a palm (after prickling me with its leg spines), then fluttered off into the jungle

a cockroach this size makes an audible thump when landing, a wonderful presence to these beasts

look at those big eyes almost meeting on top of the head!

Uncharismatic Fact of the Day

The rhinocerus cockroach got its name for a good reason-- it's the largest species of cockroach in the world. These guys can be as long as 80 mm (3.1 in), and weigh a whopping 35 g (1.2 oz). Because of their large size, they are also one of the few species of cockroach that lack wings.
