Entomological Society of Malta - vol. 4 launch

Last Friday saw the launch of the 4th volume of ESM's excellent series of papers dealing with, as the name of the society implies, the entomology of the Maltese islands and their biogeographic context.

The event was held under the patronage of His Excellency Dr. George Abela, and three society members (including its chairman) delivered short speeches on the importance of scientific research, peer reviews, funding and the maintenance of high publication standards. 

The scope of the talks ranged from the general, all-encompassing importance of works by luminaries such as Max Planck and Thomas Kuhn, to the specialized methodologies employed by scientists dealing in what the public may perceive as the "dinja stramba ta' dud, nemel u nsetti oħra" (lit. strange world of bugs, ants and other insects).

On to the main issue at hand - and its contents. This collection contains:

1) a catalogue of the aphid species occurring in Malta, with 48 new records, together with a list of aphid parasitoids, with three new records, and a new record of a coccid

2) observations and records of tachinid, rhinophorid and cecidomyiid flies from Malta and other Mediterranean areas

3) observations and records of nepticulid and pyralid moths from Malta

4) a catalogue of Maltese Scarabeoidea with eight new records, with a discussion on possible extinction mechanisms for these very interesting beetles

5) short features aimed at the younger demographic

Into the forests of Liberec

Along a stream, dewdrops on a delicate horsetail (Equisetum sp.) capture sunlight, scattering it into a miniature forest buzzing with insect life, amongst which is the common yet striking Pyrrhocoris apterus (Linnaeus, 1758). This heteropteran frequently shows aggregating behaviour and is found large populations, here photographed on the bark of the Czech national tree Tilia cordata Mill.

The periphery of the forest is characterized by a colourful scatter of berry clusters belonging to rowan (Sorbus aucuparia L.) and elder (Sambucus nigra L.), both of which have been traditionally used for food and medicine by settlers all over Europe. Further into the forest, as shade and shelter become predominant, ferns and mosses cover most of the clearing and make use of the abundant leaf litter.

Ferns on the forest floor

Conifers of the area include pines (Pinus sylvestris L.) and spruce (Picea abies (L.) H.Karst), sometimes bearing evidence of food-seeking woodpeckers on their old trunks. Angiosperms such as beech (Fagus sylvatica L.) are also common, with their deceased offering an excellent resource for several fungal specimens.

Nymphalis antiopa (Linnaeus, 1758) and Vanessa atalanta (Linnaeus, 1758) are two beautiful and conspicuous butterflies found within the forest and elsewhere.

A dead specimen of the European slow-worm Anguis fragilis Linnaeus, 1758 was a surprising find, and one of the very few vertebrates making an appearance on the day.

Entomological Society of Malta - vol. 3 launch

The launch of the annual third volume of papers in the excellent series by the Entomological Society of Malta took place this evening at the sumptuous Casino Maltese in Valletta. The occasion consisted of short talks and a presentation on what is included in this journal, entitled Bullettin of the Entomological Society of Malta.

The contents of this issue are:
1) A first Maltese record of a non-pollinating wasp of Ficus sp.
2) A review of the tineid moths from Malta including the description of a new species - Euthria melitensis Gaedike & Zerafa, 2010
3) A review of the Maltese Heteroptera with seven new records
4) A survey of potentially disease-carrying mosquito species in Malta
5) A review of the weevils of the Maltese Islands with 51 new records
6) A section aimed at young entomologists

Another moth was described in the second issue of the journal from 2009; this was Stichobasis postmeridianus, shown below. Both are, as far as is known, endemic species.

Tourism & Biodiversity

The 27th of September is World Tourism Day. The Malta Tourism Authority is celebrating this year's theme - "Tourism & Biodiversity" - by issuing a set of four stickers which feature typical organisms of the Maltese Islands.

Understandably, the variety of flora and fauna pictured is diverse and includes a plant, two invertebrates, and two vertebrates. These are, respectively:

1. Capparis orientalis Veillard (noted on the sticker under the synonym Capparis spinosa L.);
2. Papilio machaon melitensis Eller, 1936 (an endemic butterfly);
3. Echinaster sepositus sepositus (Retzius, 1783);
4. Epinephelus marginatus (Lowe, 1834) (noted on the sticker under the synonym Epinephelus guaza L., 1758);
5. and the Maltese national bird Monticola solitarius L., 1758.

Another garden visitor

It's another butterfly - smaller and much less conspicuous than its relative which I wrote about this week - yet just as beautiful and interesting. According to Sammut's definitive book on the Maltese butterflies and moths, this is Syntarucus pirithous (L., 1767), which is frequently encountered throughout the warm season.

A lepidopteran pit stop

A frequent migrant in June is the elegantly-named butterfly Vanessa (Cynthia) cardui (L., 1758), passing over Malta from North Africa on the way to cooler European climates. The following pictures, taken yesterday in Santa Venera, show a very small sample of hundreds of individuals feeding on the nectar of cultivated plants, before continuing their journey. They seem to prefer the Lantana shrubs above anything else, though this may be because of the flowers' bright yellow colour - purple-flowered Lantana shrubs were hardly visited.

Sinister sphinxes?

Hyles (Rommeliana) sammuti Eitschberger, Danner & Surholt, 1998 -

Buskett 11.XI.2009

This is the larva (caterpillar) of an endemic moth from one of the most aesthetically pleasing families in the Lepidoptera, namely the Sphingidae. Before its description in 1998, Maltese specimens belonging to Hyles sammuti Eitschberger, Danner & Surholt, 1998 were thought to belong to Hyles euphorbiae (L., 1758), a common Mediterranean species, due to similar morphology and habitat.

An adult specimen of H. sammuti may be seen below, this photograph is taken from the excellent Sphingidae of the Western Palearctic website.

The sphingids found on the Maltese islands also count amongst their ranks the infamous Acherontia atropos, (L. 1758) - undoubtedly the most famous lepidopteran amongst cinema buffs worldwide.
