phyllocnistis citrella

The citrus leafminer is a very small, light coloured moth that arrived in California from Mexico in 2000 and has now spread throughout most of California. I’ve never seen an adult, but the larval action is very evident in my yard, especially on the young lime trees. They only infest fresh growth, which of course is just about all a little tree has!

I’ve been removing the affected leaves, but today I read that it’s not a good idea, because it just creates even more fresh growth for the larvae to mine. Apparently the insects will die off over the cooler months; here’s hoping, too, that natural predators come along to help create balance.

lagopus lagopus

Willow ptarmigans (Lagopus lagopus) in the Arctic change colour throughout the year, from completely brown in mid-summer to completely white in mid-winter. The transition (which starts from the head and moves down) is triggered by changing day length, not by temperature.

With a warming Arctic, we are now seeing snow-white birds in a snow-less landscape. Where once they were perfectly camouflaged as the seasons changed, now they are sitting ‘ducks’ for predators. The climate change is happening too quickly for them to evolve to meet the new conditions.

The willow ptarmigan’s scientific name, Lagopus lagopus is derived from Ancient Greek lagos (λαγως) ‘hare’ + pous (πους) ‘foot’, in reference to the bird’s feathered feet which allow it to negotiate frozen ground.

Thanks, Max Romey, for introducing me to this bird and its story.

halconia immanis

This big beauty is high on the bathroom wall in our current lodgings, quietly minding her own business.

Lisa Vankula-Donovan (on Instagram as @wannabe_entomologist) is my hunstman-whispering hero. I don’t know how she gets them to walk calmly over her; they usually scoot rapidly away when approached.

tropical beauties

I think this Golden Orb Weaver is Trichonephila plumipes, sometimes called a Tiger Spider. Its web glows yellow, and the legs are a light orange colour, black at the joints. Big spiders are so impressive! This type is not confined to the tropics, so I hope to see more when travel to the sub-tropics.

There are some 750 different types of pandanus; I have no idea which one I was sketching! I love their aerial prop roots.

acacias

I did a bit of an audit on the acacias on my sister’s bush block. I counted five different species, four of which I am pretty confident on the ID. The fifth remains unidentified.

There are almost 1000 species of acacia in Australia!
