Wolfgang Amadeus Mozart toured Italy with his father Leopold three times between 1769 and 1773. The first, financed by performances for the nobility and by public concerts, was an extended tour of 15 months to a number of major Italian cities. The second and third journeys were to Milan, for Wolfgang to complete operas that had been commissioned there on the first visit. From the perspective of Wolfgang's musical development the journeys were a considerable success, and his talents were recognised by honours which included a papal knighthood and memberships in leading philharmonic societies. Each of Wolfgang's operas written for Milan's Teatro Regio Ducal was a critical and popular triumph. In the course of the three visits he met many leading musicians in Italy, including the renowned theorist Giovanni Battista Martini, under whom he studied in Bologna. Leopold also hoped that Wolfgang, and possibly he himself, would obtain a prestigious appointment at one of the Italian Habsburg courts. This objective became more important as Leopold's advancement in Salzburg became less likely; but his persistent efforts to secure employment displeased the imperial court, which precluded any chance of success. The journeys thus ended not with a triumphant return, but on a note of disappointment and frustration. (more...)

The cryptic mantis (Sibylla pretiosa) is a mantid native to southern Africa. Its common name comes from its ability to grow asymmetrically to match the vegetation of its environment. They have unusual leaf-like projections on the joint of their four walking legs and leaf-like wings, generally the only green portion of the insect's otherwise brown and mottled exoskeleton. Adult females grow to 5–6 cm (2.0–2.4 in) in length while the males are generally about 1 cm smaller.
