They pollinate the massive host tree, Indian laurel fig (Ficus microcarpa), producing seeds & seedlings on Palomar College campus. In fact, this Asian species is considered to be invasive in southern Calif. Its spreading root system can buckle pavement & damage underground utilities. Indian Laurel Fig Wayne's Trivia Note #955 Richard Dawkins said figs & their symbiotic wasps are the most complex of his fascinating stories. My obsession with this topic began about 40 years ago teaching botany at Palomar. I always thought each of the 876 fig species had its own wasp. New evidence indicates there may be more than one symbiotic wasp per fig. In fact, some wasps may exibit "host sharing" visiting multiple fig species. This might be happening on Palomar campus! Wayne's Trivia Note #956 Honey bees make remarkable "Bee Glue" or PROPOLIS by mixing resin exudate with saliva & beeswax. It is used as antibiotic sealant & insulation for their hive. I can testify that they were not collecting pollen from small yellow male cones. They scrape resin off leaves with mandibles and carry it in pollen baskets on hind legs. [This is also where they carry pollen.] I stood in the middle of their swarm with impunity as they collected resin. Wayne's Trivia Note #957 This painted Bo Tree (Ficus religiosa) leaf was sent to me by a former student traveling in India. Since the leaf of this sacred fig was completely skeletonized (with only venation showing), the colorful image shows up best on a black background. Wayne's Trivia Note #958 San Marcos Gabbro, a dark, granite-like, bedrock in hills bordering Twin Oaks Valley that contains iron & weathers into reddish Las Posas Clay. Some rare wildflowers in San Diego County are endemic to this soil, including the beautiful San Diego Thornmint in hills above my home. Wayne's Trivia Note #959 Explanation for figs growing in palms at Palomar College. This requires a pollinator fig wasp & bird or fruit-eating bat, a common phenomenon in tropical regions where many animals disperse the fig seeds; however, they all require symbiotic fig wasps for tasty seed-bearing "fruits" (syconia) to develop! I found 3 species of Australian fig wasps at Palomar. Several species also occur in Balboa Park & the San Diego Zoo. Without fig wasps, fig trees cannot produce seedlings. Wayne's Trivia Note #960 Trio Valadez at yesterday's Sunday Brunch (16 Feb. 2025), Cocina del Charro, San Marcos. Their rendition of the Ben E. King song "Stand by Me" was fabulous. Harp & Guitars together are incredibly beautiful for such a great song. All text material & images on these pages copyright © W.P. Armstrong
