I was happy to see this huge lawnmower cleaning up the tall grass along the road. Ticks hide in it and when you walk your dog the tick will wait for the dog to brush up against the weeds and the tick will grab on to the dog. Thanks for the info. Jeff.
Popped over to Felixstowe and couldn't resist a crack at this shot, a la Justin Minns ! A bit too much spray and waves though to get down low and close !

Black swallowtail caterpillar showing orange osmeterium partly everted - the defensive organ found in all stages of growth of papilionid larvae. It is everted when the larva feels threatened, perhaps as I had the macro lens a little too close!
The everted organ resembles a fleshy forked tongue not unlike a snake tongue and this along with the large eye like spots on the body might be used to startle birds and small reptiles.

Colonial defence comes in many forms, but fledgling settlements often start with turrets before they outfit their militas with starfighters and the like. Targeting is computer assisted, technique easy to learn and the weapons are often potent enough to dissuade pirates from attacking either by ground or air.
Against a more professional opponent, however, static turrets are easy prey to orbital sniping and can only form part of a broader defence tactic, including ships and planetary shielding.
The glandular hairs of the Saxifrages probably evolved to defend the vulnerable buds by trapping tiny insects without impeding pollinators from flying to the flowers once they open, although in his extensive work on carnivorous plants Charles Darwin suggested they also dissolve and digest the insects they trap. He tells us that in 1875 Druce reported in the Pharmaceutical Journal that he found tiny insects on almost all of the dozens of plants of Saxifraga tridactylites he examined, and a friend in Ireland found the same.
This little specimen of Rue-leaved Saxifrage (Saxifraga tridactylites) was on a mossy wall by Nottingham's NG2 Business Park
