Size Does Not Matter

Remember: click on the photos to enlarge

Wandering around the rainforest at night always reveals something of interest. Recently in the Daintree there was a "Sipyloidea" night. It seemed everywhere you looked there were Sipyloidea stick insects.
At least 3 species of Sipyloidea were found at the same place and on the same plant. Perhaps, the fragrance of the new vegetation was the attractant or, perhaps, pheromones from the individuals kept attracting additional sticks. Above we see a green species, S. rentzi, and a brown one, probably S. caeca. Other individuals are to the right. S. larryi was also present on the same plants. Most seemed to be feeding on the new vegetation, others were just sitting in one spot.

However, the evening was not such a success for one of the large individuals of S. larryi.
This stick is not dangling in mid air. It is being held by a predatory stink bug, family Pentatomidae.

The bug has inserted its beak into the unwary stick and virtually paralysed it without any visible resistance from the host. It will suck what it needs and then drop the stick which will land on the ground and probably be consumed by ants or other scavengers.

Take Home Message
Be careful on those seemingly pleasant forays after dark.
Not all Stink Bugs are damaging to your veggies!

May we display your header on our new site directory. As it is now, the site title (linked back to your home page) is listed, and we think displaying the header will attract more attention. In any event, we hope you will come by and see what is going on at SiteHoundSniffs.com.

Such lovely pics. But should that have been Striped possum (not spotted) at centenary lakes??
