This compact and sharply-painted small swallowtail is one of summer’s brightest and commonest sprites through western lowlands and foothills. Note the blunt, comparatively short wings, and the clearly defined markings. The similar Bruce’s Swallowtail (Papilio brucei Edw.) has more blue in the wings and is found mainly in the mountains. The similar Oregon Swallowtail (Papilio oregonia Edw.) does not have the wings bordered so widely with black. The design of the yellow spots is very distinctive when studied closely.

The brilliant red and purple color of this butterfly is typical of many tropical butterflies. These lovely creatures drift through the jungles and savannahs of Central and South America like great flying flowers, adding a fairy-like quality to the tropics not found in the colder north. At dung and mud puddles along the roadways you see these butterflies gathering in dozens and even hundreds, risking up in rainbow clouds when you approach.

Cardiac valve disease normally occurs from valve vegetation or thickening (Ferri, 2018). Most valve damage occurs in the pulmonary valve followed by the aortic valve (Singhi & Kumar, 2015). Rheumatic heart disease is the most common cause of cardiac valve disease and is a major cause of heart failure in children and adults (Nkoke, et al., 2016). Rheumatic heart disease is caused by Group A streptococcal infections that are not treated or not completely treated (Nkoke, et al., 2016). Most valve disease seen in the adult population is rheumatic in etiology and could have been prevented if the underlying infection would have been treated (Moreas and Tarasoutchi, 2014). There is also a chance of congenital heart disease affecting the valves of the heart. Congenital heart disease occurs at a rate of 6-8 per 1,000 live births, with 15-20% of children having valvular involvement (Singhi & Kumar, 2015).

In the west this lovely butterfly flies in the woods and brush along streams, circling lazily in the sun or dropping down to luxuriously stretch its wings upon a leaf. Try to catch it, however, and it flies off with great speed, dipping up and down in flight or even flinging itself skyward in a great leap that may take it out-of-sight. Often the orange tips of the wings flash in the sunlight in a way that must be confusing to a bird trying to catch the butterfly, for the movement of the wings causes this flashing of color to appear and then disappear.

Up and over, down and up, now you see it an now you don’t, so flashes the Long-tailed Skipper, in an out of the bushes and flowers. But suddenly you see it lighting on a beautiful flower like a thirsty boy or girl lighting on an ice-cream soda. Its whole body quivers with ecstacy as the long tongue sips up the nectar. Now you can catch it while it is so forgetful, though that would be really not sporting!
