I observed Eurema caterpillars defoliating a Serianthes nelsonii sapling growing at the University of Guam Agricultural Experiment Station in Yigo.
On November 19, Joe Cruz brought in some onion leaves with apparent thrips damage. Managed to find one thrips but it did not look like the usual suspects.
This thrips was first detected on Guam early in 2012. This is a South American species which has spread to the Caribbean and Florida. To date, it has not been found in California or Hawaii.
More info to be posted here in the near future.
"Swezey (1946) recorded the life history of a Eumelea on Guam that
he attributed to rosalia Stoll. Material from Guam in the BMNH is
referable to ludovicata. The host plant was also Macaranga."

Olympia Terral brought in a sphinx moth that had died with its proboscis trapped in a ginger lily flower. At first it appeared that the proboscis was stuck between the calyx and carolla. However, carefull microscopic examination revealed that the proboscis had been inserted deep into a flower. The carolla of this flower had died and shrunk, tightly enshrouding the proboscis. Dissection of the corolla showed that it is lined with downward-angled hairs. These hairs may have caused enough friction to prevent the moth from withdrawing its proboscis.
Olympia has seen this phenomenon several times on Guam and similar observations have been previously reported elsewhere:
There were a large number of white-footed ants, Technomyrmex albipes, tending aphids, Pentalonia caladii, in these flowers.
