Claim: Extreme weather decides distribution of insects

I am the wrong one, i should have read more carefully, this is the trouble, i see these articles and switch off.
“In fact, our predictions are that some species would disappear entirely in the next few decades,

..and yet mosquitoes (malaria) will take over the world

Whenever we see articles like these people point to adaptation, acclimatization and migration. Here are some on abstracts on acclimatization of the fruit flies Drosophila which may or may not mean they could cope with the modeled computer temperature predictions for Australia in 2100. We’ll know in 87 years.

Abstract
Heat-shock tolerance and inbreeding in Drosophila buzzatii
…..All flies were conditioned at 36.5°C for 75 min prior to exposure to stress, to activate the synthesis of heat-shock proteins. These proteins are known to protect cells against stress damage. The younger group of flies were exposed to a thermal stress of 40.7°C for 88 min, 103 min, or 118 min and the older flies to the same temperature only for 88 min or 103 min, as the survival of older flies after heat stress was much lower than that of the younger flies…….

Abstract
Effects of inbreeding in three life stages of Drosophila buzzatii after embryos were exposed to a high temperature stress.
…The interaction between inbreeding and high-temperature stress was examined in the cactophilic fruit fly, Drosophila buzzatii. Embryos of four inbreeding levels (F = 0, F = 0.25, F = 0.375, F = 0.5) were either maintained at 25°C throughout egg-to-adult development or were exposed to 41.5°C for 110 min at an age of 20 h. Hatching, larva-to-pupa survival, pupato-adult survival, and egg-to-adult survival were estimated. Heat shock reduced hatching rates, but survival to adulthood for individuals that hatched was unaffected by the heat shock……

Abstract
Effects of extreme temperatures on phenotypic variation and developmental stability in Drosophila melanogaster and Drosophila buzzatii
…….Drosophila melanogaster and Drosophila buzzatii. In both species, a general trend for increasing of phenotypic variation and fluctuating asymmetry at stress temperatures was observed; in fluctuating asymmetry, this effect was more pronounced……

UK butterflies are threatened by global warming.

BBC – 16 September 2013
Hot summer helps boost butterflies
…………
The sustained warm weather over the summer provided “perfect” conditions for a boom in butterflies and day-flying moths according to experts.
“Put simply, butterflies are cold-blooded creatures that rely on the warmth of the sun in order to be active,” said Butterfly Conservation’s survey manager Richard Fox.
“The hot summer this year meant that some butterfly species, which were in their early life cycle stages when the heat wave began were able to capitalise on it giving rise to high numbers of adults during the count in late July and early August.”…..

Why plan to kill fruit flies with spraying when climate change will kill them anyway? OK it’s a different fruit fly but the article above does mention insects in general towards the end.

IPCC TAR – Working Group II: Impacts, Adaptation and Vulnerability
12.5.7. Pests and Diseases
Cropping, horticulture, and forestry in Australia and New Zealand are vulnerable to invasion by new pests and pathogens for which there are no local biological controls (Sutherst et al., 1996; Ministry for the Environment, 1997). The likelihood that such pests and pathogens—particularly those of tropical or semi-tropical origin—will become established, once introduced to New Zealand, may increase with climate warming.

…..The vulnerability of horticultural industries in Australia to the Queensland fruit fly Bactrocera (Dacus) tryoni under climate change was examined by Sutherst et al. (2000). Vulnerability was defined in terms of sensitivity and adaptation options. Regional estimates of fruit fly density, derived with the CLIMEX model, were fed into an economic model that took account of the costs of damage, management, regulation, and research. Sensitivity analyses were used to estimate potential future costs under climate change by recalculating costs with increases in temperature of 0.5, 1.0, and 2°C, assuming that the fruit fly will occur only in horticulture where there is sufficient rainfall or irrigation to allow the crop to grow. The most affected areas were the high-altitude apple-growing areas of southern Queensland and NSW and orange-growing areas in the Murrumbidgee Irrigation Area. Apples and pears in southern and central NSW also were affected. A belt from southern NSW across northern Victoria and into South Australia appeared to be the most vulnerable.
Adaptation options were investigated by considering, first, their sustainability under present conditions and, second, their robustness under climate variability and climate change. Bait spraying is ranked as the most sustainable, robust, and hence most promising adaptation option in boh the endemic and fruit fly exclusion zones, but it causes some public concern. The sterile insect technique is particularly safe, but there were concerns about costs, particularly with large infestations. Exclusion is a highly effective approach for minimizing the number of outbreaks of Queensland fruit fly in fly-free areas, although it is vulnerable to political pressure in relation to tourism. These three techniques have been given the highest priority…..

I’d like to send the authors a list of the insect species I would prefer be extinct, but I don’t have the time for such a long list.

Abrupt Climate Change: Inevitable Surprises 2002
Executive Summary
Recent scientific evidence shows that major and widespread climate changes have occurred with startling speed. For example, roughly half the north Atlantic warming since the last ice age was achieved in only a decade, and it was accompanied by significant climatic changes across most of the globe. Similar events, including local warmings as large as 16°C, occurred repeatedly during the slide into and climb out of the last ice age.

Well in the USA they say that the Eastern Elk have gone extinct. Apparently the only thing bigger than an ant that has; except nobody has seen that Woody wood pecker in the swamp for a while.
Well come out to California, if you want to see an Eastern Elk; we have plenty of them. They don’t go back East any more, because it is too hard to cross all the roads, because of traffic.
Come to think of it, you can see Eastern Elk down in New Zealand; try asking for Wapiti though, or else they won’t know what you are talking about. They are about as extinct as the San Francisco Bay Coyote, which eats Clapper Rails. I have all kinds of San Francisco Bay Coyotes hanging out, down by my house, south of Fresno.
