blue weevil!

Last weekend we went for a walk to the Bosque da Ciencia. It was a short visit but we found a beautiful beetle, a blue weevil!   It is a broad-nosed weevil (Curculionidae: Entiminae) with some blue on its legs and antenna.

This weekend we went for a walk to the Reserva Duke, in the northern part of Manaus. Part of the reserve is a botanical garden (Jardim Botanico) with nice trails in the forest and new exhibition areas in the forest.  I really liked the little pirarucu we saw, it was just a few months old, and about 20 cm long.  I will write a post about them later on.  While we were looking at the exhibit about frogs and toads, I saw a beetle on the floor.  I stopped paying attention to the frogs at that point.  Here’s what I saw:

Long-horn beetle

This long-horn beetle (Cerambycidae) was near one of the room doors of the Arawak hostel in Praia do Açutuba, Iranduba, Amazonas.  The hostel was the meeting point for the Grupo de Fotografia Manaus March trip.  Every month, on the first Sunday, a trip is organized, to a park, a special event or a nearby site like the beach where we went two weeks ago.

I went to spend a couple of days out in the field, that is the Amazon forest, as there was going to be a good churrasco and fishing the next day.  Both were delicious meals!  This beetle was floating on a little stream, we took it out and I took some pictures of it.  It was complicated because of the color and it was so bright out.  Different light conditions provide with a challenge when taking pictures.  It was a good practice, I think it came out very nice.


leaf-cutter ant

One of the reasons I was so excited to come live here in Manaus was for all the insects I could encounter here.  However, there are some that have given us trouble, and I’m thinking about ants.  There are many species of ants in the garden and house, some are eating one of the bedroom doors, others decided that they like the dog food and sometimes the plate is covered with ants and other little ones just like sweet stuff, but those don’t bother me that much, except when my juice glass gets covered by them.  Then there are many others in the garden.  Those that like dog food, seem to like everything, I have seen them taking chicken feathers into their nest.  but the worst are leaf-cutter ants!  They have cut leaves of so many of our plants, just in one night the hibiscus were without leaves, and then they went for the nonis, and they have also gone up the mango tree.  However, with so many of them I had the chance to practice taking photographs of moving insects. It has been complicated as they move so fast and so much.  It’s the first time I try using a white background thanks to some macrophotography tips shared by my friend The Bug Geek.

Amazon blue insects

A couple of pictures of blue insects that I saw while visiting some waterfalls near Presidente Figueiredo, about 100 km north of Manaus.  While others were happily swimming and refreshing themselves from the tropical heat, I took some time to look around for insects (as I usually do) and was happy to found two blue ones.  I like blue insects, as my blog name suggests.  This photographs were taken in April last year!  I finally got to upload them to the blog.  I really have to keep up with this.

Just emerging after developing on the little pond in the garden.

I think it’s a species of Orthemis, in the Libellulidae family. The males are very territorial and usually red or purple colored, whereas the females are dark brown.  I’ve seen females laying eggs in the pond, and the male looking over his territory from some branches nearby.  This dragonfly was seen on Eichhornia, the water hyacinths we have on the pond, Saturday October 15, 2011.


holding on

any ideas on what this insect is?

Garden, Jardim Paulista, Manaus

IT’S A BEE! It belongs to the tribe Ericrocidini.  It was suggested that it can be a specimen of Mesocheira bicolor. However, I am not sure of the species yet.  These bees are parasitic of other bees, they lay their eggs on the nest of other bees.  They wait near the entrance to the nest on the ground, and when they see the adults leave the nest, the female goes in and lays her eggs in there.

The males have this behavior of hanging on vegetation for the night, they release pheromones and usually other males come and they spend the night in groups protected by the vegetation.  I was told that the males come back to the same area to spend the night, so I will try to look for it or more around the garden tonight, I might have luck and find it again.
