Dry Times

This week has been consistently dry and sunny with only the slightest of rain falling at night.  If these conditions continue then it won’t be long before the trees start to flower.  We should then start to see an increase in particularly of insect numbers.  There is already the beginnings in cicada sound.  By January and February the sound will be deafening.

Not The Usual Suspect

While out on my weekly butterfly count last week I saw a small pale colored butterfly flitting slowly through the forest close to the ground.  I was pretty sure I knew what it was but there was something that was allowing a small amount of doubt to creep in.  The butterfly had settled on a leaf some distance away from the trail and amongst a tangle of vegetation the disturbance of which I am positive would have sent the creature to flight once more.  Fortunately I had a 300mm lens on the camera so I could get a shot of the butterfly for identification purposes.  Once I returned, download the image and cropped it to a reasonable size then my suspicions were confirmed.  The butterfly was Euptychia insolata and this was not a species I had recorded at Bosque before.


Not long before the above sighting I had just finished photographing another satyr, Cissia confusa.  Many of the butterflies found flying around the grounds of Bosque are very brightly colored to the point of garish.  You cannot fail to notice a host of different species of Longwing butterflies that can be seen flitting from flower to flower on the Lantana bush a short walk from the restaurant.  They produce a non-stop moving picture show of reds, oranges, yellows and black.  Flying along the forest paths are the spectacular and dazzling morphos.  Their brilliant iridescent blues flash in the gloomy understory of the forest like an azul strobe.


The satyrs on the other hand are much more subtle.  The soft pastel shades of brown, tan and muted oranges serve to render them indistinquable from the leaves on the forest floor.  My preference is for the warm browns rather than the hot reds.

Little Blue

There is a small herbaceous plant that grows around Bosque that, although it doesn’t attract as many butterflies as the Lantana, is still visited by a variety of species, namely the skippers.  This is the Porterweed, Staphytarpheta frantzii.  The small lavender blue flowers are borne on green spike.  It likes more open sunny areas in which to grow.
