Moth time

Moths get a really bad name, but I think they easily rival our butterflies for beauty and certainly for diversity (and for difficulty of identification - although the next few are easy enough).

This is the Small Magpie - Eurrhypara hortulata, which feeds primarily on Nettle:


The Cinnabar moth - Tyria jacobaea - is one of the most readily identifiable moths and is dependant on Ragwort:
A word about Ragwort: Ragwort is often blamed for the deaths of horses and cattle. I have spoken to many local farmers and they are unanimous that all animals will avoid eating Ragwort if it is left to grow. If the plant is pulled from the ground and left to 'sweeten', then animals can't differentiate it from hay and will eat it. That's when deaths occur. Leave Ragwort alone and it won't cause problems to animals, and will continue to nurture insects such as moths, hoverflies and bees.

The Brimstone Moth - Opisthograptis luteolata - has a fascinating life-cycle which enables it to adapt to varying winter conditions. Sometimes it overwinters as a larva; at other times as a pupa, the emergence date being governed by the type of overwintering strategy. It can be found as an adult from April to October, with some evidence for three generations over 2 years. Foodplants are shrubs and bushes such as Hawthorn and Blackthorn.


The most frequent leaf-miner on my patch is the micromoth Stigmella aurella, which makes leaf-mines on Bramble (and occasionally, on Meadowsweet). This is the (3mm!) adult:


Tachinid flies are parasitic on moth and butterfly larvae. This one became lunch for a Dung Fly. It's tough out there.


For some reason, this cock Bullfinch took a fancy to my rear door. It repeatedly flew at the rear window and then returned to the hosepipe winch. Perhaps it thought it saw a competitor in its reflection.

Dry night - moths to light

Plenty of moth activity due to the dry days/nights.

This is the Brimstone Moth - Opisthograptis luteolata:


The rather frequent Buff Ermine - Spilosoma luteum.


Difficult to catch the subtle blue colouring of the Clouded Silver - Lomographa temerata - under flash:



And finally for today, the orange form of Common Marbled Carpet - Chloroclysta truncata.


When identifying moths, pattern is virtually everything. Colour is much less important. And this specimen is VERY worn.
